//	Implementation Summary
//
//	1. Enforce API surface and semantic compatibility with 1.9.x branch
//	2. Improve the module's maintainability by reducing the storage
//		paths to a single mechanism.
//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)
//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

 * This object provides a utility for producing rich Error messages within
 * Angular. It can be called as follows:
 *
 * var exampleMinErr = minErr('example');
 * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
 *
 * The above creates an instance of minErr in the example namespace. The
 * resulting error will have a namespaced error code of example.one.  The
 * resulting error will replace {0} with the value of foo, and {1} with the
 * value of bar. The object is not restricted in the number of arguments it can
 * take.
 *
 * If fewer arguments are specified than necessary for interpolation, the extra
 * interpolation markers will be preserved in the final string.
 *
 * Since data will be parsed statically during a build step, some restrictions
 * are applied with respect to how minErr instances are created and called.
 * Instances should have names of the form namespaceMinErr for a minErr created
 * using minErr('namespace') . Error codes, namespaces and template strings
 * should all be static strings, not variables or general expressions.
 *
 * @param {string} module The namespace to use for the new minErr instance.
 * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning
 *   error from returned function, for cases when a particular type of error is useful.

 *
 * Two objects or values are considered equivalent if at least one of the following is true:
 *
 * * Both objects or values pass `===` comparison.
 * * Both objects or values are of the same type and all of their properties are equal by
 *   comparing them with `angular.equals`.
 * * Both values are NaN. (In JavaScript, NaN == NaN => false. But we consider two NaN as equal)
 * * Both values represent the same regular expression (In JavaScript,
 *   /abc/ == /abc/ => false. But we consider two regular expressions as equal when their textual
 *   representation matches).
 *
 * During a property comparison, properties of `function` type and properties with names
 * that begin with `$` are ignored.
 *
 * Scope and DOMWindow objects are being compared only by identify (`===`).

 *   created in "strict-di" mode. This means that the application will fail to invoke functions which

 *
 * @description
 *
 * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
 * designates the **root element** of the application and is typically placed near the root element
 * of the page - e.g. on the `<body>` or `<html>` tags.
 *
 * There are a few things to keep in mind when using `ngApp`:
 * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
 *   found in the document will be used to define the root element to auto-bootstrap as an
 *   application. To run multiple applications in an HTML document you must manually bootstrap them using
 *   {@link angular.bootstrap} instead.
 * - AngularJS applications cannot be nested within each other.
 * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
 *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
 *   {@link ngRoute.ngView `ngView`}.
 *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
 *   causing animations to stop working and making the injector inaccessible from outside the app.
 *
 * You can specify an **AngularJS module** to be used as the root module for the application.  This
 * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
 * should contain the application code needed or have dependencies on other modules that will
 * contain the code. See {@link angular.module} for more information.
 *
 * In the example below if the `ngApp` directive were not placed on the `html` element then the
 * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
 * would not be resolved to `3`.
 *
 * `ngApp` is the easiest, and most common way to bootstrap an application.
 *
 <example module="ngAppDemo" name="ng-app">
   <file name="index.html">
   <div ng-controller="ngAppDemoController">
     I can add: {{a}} + {{b}} =  {{ a+b }}
   </div>
   </file>
   <file name="script.js">
   angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
     $scope.a = 1;
     $scope.b = 2;
   });
   </file>

 * @ngdoc function

 * @description
 * Use this function to manually start up angular application.
 *
 * For more information, see the {@link guide/bootstrap Bootstrap guide}.
 *
 * Angular will detect if it has been loaded into the browser more than once and only allow the
 * first loaded script to be bootstrapped and will report a warning to the browser console for
 * each of the subsequent scripts. This prevents strange results in applications, where otherwise
 * multiple instances of Angular try to work on the DOM.
 *
 * <div class="alert alert-warning">
 * **Note:** Protractor based end-to-end tests cannot use this function to bootstrap manually.
 * They must use {@link ng.directive:ngApp ngApp}.
 * </div>
 *
 * <div class="alert alert-warning">
 * **Note:** Do not bootstrap the app on an element with a directive that uses {@link ng.$compile#transclusion transclusion},
 * such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and {@link ngRoute.ngView `ngView`}.
 * Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
 * causing animations to stop working and making the injector inaccessible from outside the app.

     * The `angular.module` is a global place for creating, registering and retrieving Angular
     * modules.
     * All modules (angular core or 3rd party) that should be available to an application must be
     * registered using this mechanism.
     *
     * Passing one argument retrieves an existing {@link angular.Module},
     * whereas passing more than one argument creates a new {@link angular.Module}
     *
     *
     * # Module
     *
     * A module is a collection of services, directives, controllers, filters, and configuration information.
     * `angular.module` is used to configure the {@link auto.$injector $injector}.
     *
     * ```js
     * // Create a new module
     * var myModule = angular.module('myModule', []);
     *
     * // register a new service
     * myModule.value('appName', 'MyCoolApp');
     *
     * // configure existing services inside initialization blocks.
     * myModule.config(['$locationProvider', function($locationProvider) {
     *   // Configure existing providers
     *   $locationProvider.hashPrefix('!');
     * }]);
     * ```
     *
     * Then you can create an injector and load your modules like this:
     *
     * ```js
     * var injector = angular.injector(['ng', 'myModule'])
     * ```
     *
     * However it's more likely that you'll just use
     * {@link ng.directive:ngApp ngApp} or
     * {@link angular.bootstrap} to simplify this process for you.
     *
     * @param {!string} name The name of the module to create or retrieve.
     * @param {!Array.<string>=} requires If specified then new module is being created. If
     *        unspecified then the module is being retrieved for further configuration.
     * @param {Function=} configFn Optional configuration function for the module. Same as
     *        {@link angular.Module#config Module#config()}.
     * @returns {angular.Module} new module with the {@link angular.Module} api.

/**
 * @ngdoc function
 * @name angular.element
 * @module ng
 * @kind function
 *
 * @description
 * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
 *
 * If jQuery is available, `angular.element` is an alias for the
 * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
 * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
 *
 * jqLite is a tiny, API-compatible subset of jQuery that allows
 * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
 * commonly needed functionality with the goal of having a very small footprint.
 *
 * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
 * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
 * specific version of jQuery if multiple versions exist on the page.
 *
 * <div class="alert alert-info">**Note:** All element references in Angular are always wrapped with jQuery or
 * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.</div>
 *
 * <div class="alert alert-warning">**Note:** Keep in mind that this function will not find elements
 * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
 * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.</div>
 *
 * ## Angular's jqLite
 * jqLite provides only the following jQuery methods:
 *
 * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
 * - [`after()`](http://api.jquery.com/after/)
 * - [`append()`](http://api.jquery.com/append/)
 * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
 * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
 * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
 * - [`clone()`](http://api.jquery.com/clone/)
 * - [`contents()`](http://api.jquery.com/contents/)
 * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
 *   As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
 * - [`data()`](http://api.jquery.com/data/)
 * - [`detach()`](http://api.jquery.com/detach/)
 * - [`empty()`](http://api.jquery.com/empty/)
 * - [`eq()`](http://api.jquery.com/eq/)
 * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
 * - [`hasClass()`](http://api.jquery.com/hasClass/)
 * - [`html()`](http://api.jquery.com/html/)
 * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
 * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
 * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
 * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
 * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
 * - [`prepend()`](http://api.jquery.com/prepend/)
 * - [`prop()`](http://api.jquery.com/prop/)
 * - [`ready()`](http://api.jquery.com/ready/)
 * - [`remove()`](http://api.jquery.com/remove/)
 * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
 * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
 * - [`removeData()`](http://api.jquery.com/removeData/)
 * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
 * - [`text()`](http://api.jquery.com/text/)
 * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
 * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
 * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces or event object as parameter
 * - [`val()`](http://api.jquery.com/val/)
 * - [`wrap()`](http://api.jquery.com/wrap/)
 *
 * ## jQuery/jqLite Extras
 * Angular also provides the following additional methods and events to both jQuery and jqLite:
 *
 * ### Events
 * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
 *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
 *    element before it is removed.
 *
 * ### Methods
 * - `controller(name)` - retrieves the controller of the current element or its parent. By default
 *   retrieves controller associated with the `ngController` directive. If `name` is provided as
 *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
 *   `'ngModel'`).
 * - `injector()` - retrieves the injector of the current element or its parent.
 * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
 *   element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
 *   be enabled.
 * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
 *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
 *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
 *   Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
 * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
 *   parent element is reached.
 *
 * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
 * https://github.com/angular/angular.js/issues/14251 for more information.
 *
 * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
 * @returns {Object} jQuery object.

 *
 * @param {Array.<string|Function>} modules A list of module functions or their aliases. See

 * Typical usage
 * ```js
 *   // create an injector
 *   var $injector = angular.injector(['ng']);
 *
 *   // use the injector to kick off your application
 *   // use the type inference to auto inject arguments, or use implicit injection

 * ```
 *
 * Sometimes you want to get access to the injector of a currently running Angular app
 * from outside Angular. Perhaps, you want to inject and compile some markup after the
 * application has been bootstrapped. You can do this using the extra `injector()` added
 * to JQuery/jqLite elements. See {@link angular.element}.
 *
 * *This is fairly rare but could be the case if a third party library is injecting the
 * markup.*
 *
 * In the following example a new block of HTML containing a `ng-controller`
 * directive is added to the end of the document body by JQuery. We then compile and link
 * it into the current AngularJS scope.
 *
 * ```js
 * var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');
 * $(document.body).append($div);
 *
 * angular.element(document).injector().invoke(function($compile) {

 * # Injection Function Annotation
 *
 * JavaScript does not have annotations, and annotations are needed for dependency injection. The
 * following are all valid ways of annotating function with injection arguments and are equivalent.
 *
 * ```js
 *   // inferred (only works if code not minified/obfuscated)
 *   $injector.invoke(function(serviceA){});
 *
 *   // annotated
 *   function explicit(serviceA) {};

 *
 *   // inline
 *   $injector.invoke(['serviceA', function(serviceA){}]);
 * ```
 *
 * ## Inference
 *
 * In JavaScript calling `toString()` on a function returns the function definition. The definition
 * can then be parsed and the function arguments can be extracted. This method of discovering
 * annotations is disallowed when the injector is in strict mode.
 * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
 * argument names.
 *
 * ## `$inject` Annotation
 * By adding an `$inject` property onto a function the injection parameters can be specified.
 *
 * ## Inline
 * As an array of injection names, where the last item in the array is the function to call.

/**
 * @ngdoc method
 * @name $injector#annotate
 *
 * @description
 * Returns an array of service names which the function is requesting for injection. This API is
 * used by the injector to determine which services need to be injected into the function when the
 * function is invoked. There are three ways in which the function can be annotated with the needed
 * dependencies.
 *
 * # Argument names
 *
 * The simplest form is to extract the dependencies from the arguments of the function. This is done
 * by converting the function into a string using `toString()` method and extracting the argument
 * names.
 * ```js
 *   // Given
 *   function MyController($scope, $route) {
 *     // ...
 *   }
 *
 *   // Then
 *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
 * ```
 *
 * You can disallow this method by using strict injection mode.
 *
 * This method does not work with code minification / obfuscation. For this reason the following
 * annotation strategies are supported.
 *
 * # The `$inject` property
 *
 * If a function has an `$inject` property and its value is an array of strings, then the strings
 * represent names of services to be injected into the function.
 * ```js
 *   // Given
 *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
 *     // ...
 *   }
 *   // Define function dependencies
 *   MyController['$inject'] = ['$scope', '$route'];
 *
 *   // Then
 *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
 * ```
 *
 * # The array notation
 *
 * It is often desirable to inline Injected functions and that's when setting the `$inject` property
 * is very inconvenient. In these situations using the array notation to specify the dependencies in
 * a way that survives minification is a better choice:
 *
 * ```js
 *   // We wish to write this (not minification / obfuscation safe)
 *   injector.invoke(function($compile, $rootScope) {
 *     // ...
 *   });
 *
 *   // We are forced to write break inlining
 *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
 *     // ...
 *   };
 *   tmpFn.$inject = ['$compile', '$rootScope'];
 *   injector.invoke(tmpFn);
 *
 *   // To better support inline function the inline annotation is supported
 *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
 *     // ...
 *   }]);
 *
 *   // Therefore
 *   expect(injector.annotate(
 *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
 *    ).toEqual(['$compile', '$rootScope']);
 * ```
 *
 * @param {Function|Array.<string|Function>} fn Function for which dependent service names need to
 * be retrieved as described above.

 * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.

 *
 * The {@link auto.$provide $provide} service has a number of methods for registering components

 *
 * An Angular **service** is a singleton object created by a **service factory**.  These **service
 * factories** are functions which, in turn, are created by a **service provider**.
 * The **service providers** are constructor functions. When instantiated they must contain a
 * property called `$get`, which holds the **service factory** function.
 *
 * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
 * correct **service provider**, instantiating it and then calling its `$get` **service factory**
 * function to get the instance of the **service**.
 *
 * Often services have no configuration options and there is no need to add methods to the service
 * provider.  The provider will be no more than a constructor function with a `$get` property. For
 * these cases the {@link auto.$provide $provide} service has additional helper methods to register
 * services without specifying a provider.
 *
 * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the
 *     {@link auto.$injector $injector}
 * * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by
 *     providers and services.
 * * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by
 *     services, not providers.
 * * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
 *     that will be wrapped in a **service provider** object, whose `$get` property will contain the
 *     given factory function.
 * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
 *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate
 *      a new object using the given constructor function.
 * * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that

 *
 * Service provider names start with the name of the service they provide followed by `Provider`.
 * For example, the {@link ng.$log $log} service has a provider called

 * and its service. Importantly, you can configure what kind of service is created by the `$get`
 * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
 * method {@link ng.$logProvider#debugEnabled debugEnabled}
 * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
 * console or not.
 *
 * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
                        'Provider'` key.
 * @param {(Object|function())} provider If the provider is:
 *
 *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using

/**
 * @ngdoc method

 * @description
 *
 * Register a **service factory**, which will be called to return the service instance.
 * This is short for registering a service where its provider consists of only a `$get` property,
 * which is the given service factory function.
 * You should use {@link auto.$provide#factory $provide.factory(getFn)} if you do not need to
 * configure your service in a provider.
 *
 * @param {string} name The name of the instance.
 * @param {Function|Array.<string|Function>} $getFn The injectable $getFn for the instance creation.
 *                      Internally this is a short hand for `$provide.provider(name, {$get: $getFn})`.
 * @returns {Object} registered provider instance
 *
 * @example
 * Here is an example of registering a service
 * ```js
 *   $provide.factory('ping', ['$http', function($http) {
 *     return function ping() {
 *       return $http.send('/ping');
 *     };

 * You would then inject and use this service like this:

 *   }]);
 * ```

 * that replaces (or wraps and delegates to) the original service.
 *
 * You can find out more about using decorators in the {@link guide/decorators} guide.
 *
 * @param {string} name The name of the service to decorate.
 * @param {Function|Array.<string|Function>} decorator This function will be invoked when the service needs to be

 *    Local injection arguments:
 *
 *    * `$delegate` - The original service instance, which can be replaced, monkey patched, configured,

 *
 * @example
 * Here we decorate the {@link ng.$log $log} service to convert warnings to errors by intercepting

   *
   * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a

   *
   * @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of

   * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
   * positioned elements at the top of the page, such as navbars, headers etc.
   *
   * `yOffset` can be specified in various ways:
   * - **number**: A fixed number of pixels to be used as offset.<br /><br />
   * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
   *   a number representing the offset (in pixels).<br /><br />
   * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
   *   the top of the page to the element's bottom will be used as offset.<br />
   *   **Note**: The element will be taken into account only as long as its `position` is set to
   *   `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
   *   their height and/or positioning according to the viewport's size.
   *
   * <br />

/**
 * @ngdoc service
 * @name $compile
 * @kind function
 *
 * @description
 * Compiles an HTML string or DOM into a template and produces a template function, which
 * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
 *
 * The compilation is a process of walking the DOM tree and matching DOM elements to
 * {@link ng.$compileProvider#directive directives}.
 *
 * <div class="alert alert-warning">
 * **Note:** This document is an in-depth reference of all directive options.
 * For a gentle introduction to directives with examples of common use cases,
 * see the {@link guide/directive directive guide}.
 * </div>
 *
 * ## Comprehensive Directive API
 *
 * There are many different options for a directive.
 *
 * The difference resides in the return value of the factory function.
 * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
 * that defines the directive properties, or just the `postLink` function (all other properties will have
 * the default values).
 *
 * <div class="alert alert-success">
 * **Best Practice:** It's recommended to use the "directive definition object" form.
 * </div>
 *
 * Here's an example directive declared with a Directive Definition Object:
 *
 * ```js
 *   var myModule = angular.module(...);
 *
 *   myModule.directive('directiveName', function factory(injectables) {
 *     var directiveDefinitionObject = {
 *       {@link $compile#-priority- priority}: 0,
 *       {@link $compile#-template- template}: '<div></div>', // or // function(tElement, tAttrs) { ... },
 *       // or
 *       // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
 *       {@link $compile#-transclude- transclude}: false,
 *       {@link $compile#-restrict- restrict}: 'A',
 *       {@link $compile#-templatenamespace- templateNamespace}: 'html',
 *       {@link $compile#-scope- scope}: false,
 *       {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
 *       {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',
 *       {@link $compile#-bindtocontroller- bindToController}: false,
 *       {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
 *       {@link $compile#-multielement- multiElement}: false,
 *       {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {
 *         return {
 *            {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
 *            {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
 *         }
 *         // or
 *         // return function postLink( ... ) { ... }
 *       },
 *       // or
 *       // {@link $compile#-link- link}: {
 *       //  {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
 *       //  {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
 *       // }
 *       // or
 *       // {@link $compile#-link- link}: function postLink( ... ) { ... }
 *     };
 *     return directiveDefinitionObject;
 *   });
 * ```
 *
 * <div class="alert alert-warning">
 * **Note:** Any unspecified options will use the default value. You can see the default values below.
 * </div>
 *
 * Therefore the above can be simplified as:
 *
 * ```js
 *   var myModule = angular.module(...);
 *
 *   myModule.directive('directiveName', function factory(injectables) {
 *     var directiveDefinitionObject = {
 *       link: function postLink(scope, iElement, iAttrs) { ... }
 *     };
 *     return directiveDefinitionObject;
 *     // or
 *     // return function postLink(scope, iElement, iAttrs) { ... }
 *   });
 * ```
 *
 * ### Life-cycle hooks
 * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
 * directive:
 * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
 *   had their bindings initialized (and before the pre &amp; post linking functions for the directives on
 *   this element). This is a good place to put initialization code for your controller.
 * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
 *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
 *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
 *   component such as cloning the bound value to prevent accidental mutation of the outer value.
 * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
 *   changes. Any actions that you wish to take in response to the changes that you detect must be
 *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
 *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
 *   be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
 *   if detecting changes, you must store the previous value(s) for comparison to the current values.
 * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
 *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
 *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
 *   components will have their `$onDestroy()` hook called before child components.
 * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
 *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
 *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
 *   they are waiting for their template to load asynchronously and their own compilation and linking has been
 *   suspended until that occurs.
 *
 * #### Comparison with Angular 2 life-cycle hooks
 * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
 * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
 *
 * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
 * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
 *   In Angular 2 you can only define hooks on the prototype of the Component class.
 * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
 *   `ngDoCheck` in Angular 2
 * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
 *   propagated throughout the application.
 *   Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
 *   error or do nothing depending upon the state of `enableProdMode()`.
 *
 * #### Life-cycle hook examples
 *
 * This example shows how you can check for mutations to a Date object even though the identity of the object
 * has not changed.
 *
 * <example name="doCheckDateExample" module="do-check-module">
 *   <file name="app.js">
 *     angular.module('do-check-module', [])
 *       .component('app', {
 *         template:
 *           'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' +
 *           'Date: {{ $ctrl.date }}' +
 *           '<test date="$ctrl.date"></test>',
 *         controller: function() {
 *           this.date = new Date();
 *           this.month = this.date.getMonth();
 *           this.updateDate = function() {
 *             this.date.setMonth(this.month);
 *           };
 *         }
 *       })
 *       .component('test', {
 *         bindings: { date: '<' },
 *         template:
 *           '<pre>{{ $ctrl.log | json }}</pre>',
 *         controller: function() {
 *           var previousValue;
 *           this.log = [];
 *           this.$doCheck = function() {
 *             var currentValue = this.date && this.date.valueOf();
 *             if (previousValue !== currentValue) {
 *               this.log.push('doCheck: date mutated: ' + this.date);
 *               previousValue = currentValue;
 *             }
 *           };
 *         }
 *       });
 *   </file>
 *   <file name="index.html">
 *     <app></app>
 *   </file>
 * </example>
 *
 * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
 * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
 * arrays or objects can have a negative impact on your application performance)
 *
 * <example name="doCheckArrayExample" module="do-check-module">
 *   <file name="index.html">
 *     <div ng-init="items = []">
 *       <button ng-click="items.push(items.length)">Add Item</button>
 *       <button ng-click="items = []">Reset Items</button>
 *       <pre>{{ items }}</pre>
 *       <test items="items"></test>
 *     </div>
 *   </file>
 *   <file name="app.js">
 *      angular.module('do-check-module', [])
 *        .component('test', {
 *          bindings: { items: '<' },
 *          template:
 *            '<pre>{{ $ctrl.log | json }}</pre>',
 *          controller: function() {
 *            this.log = [];
 *
 *            this.$doCheck = function() {
 *              if (this.items_ref !== this.items) {
 *                this.log.push('doCheck: items changed');
 *                this.items_ref = this.items;
 *              }
 *              if (!angular.equals(this.items_clone, this.items)) {
 *                this.log.push('doCheck: items mutated');
 *                this.items_clone = angular.copy(this.items);
 *              }
 *            };
 *          }
 *        });
 *   </file>
 * </example>

 *
 * ### Directive Definition Object
 *
 * The directive definition object provides instructions to the {@link ng.$compile
 * compiler}. The attributes are:
 *
 * #### `multiElement`
 * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
 * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
 * together as the directive elements. It is recommended that this feature be used on directives
 * which are not strictly behavioral (such as {@link ngClick}), and which
 * do not manipulate or replace child nodes (such as {@link ngInclude}).
 *
 * #### `priority`
 * When there are multiple directives defined on a single DOM element, sometimes it
 * is necessary to specify the order in which the directives are applied. The `priority` is used
 * to sort the directives before their `compile` functions get called. Priority is defined as a
 * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
 * are also run in priority order, but post-link functions are run in reverse order. The order
 * of directives with the same priority is undefined. The default priority is `0`.
 *
 * #### `terminal`
 * If set to true then the current `priority` will be the last set of directives
 * which will execute (any directives at the current priority will still execute
 * as the order of execution on same `priority` is undefined). Note that expressions
 * and other directives used in the directive's template will also be excluded from execution.
 *
 * #### `scope`
 * The scope property can be `false`, `true`, or an object:
 *
 * * **`false` (default):** No scope will be created for the directive. The directive will use its
 * parent's scope.
 *
 * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
 * the directive's element. If multiple directives on the same element request a new scope,
 * only one new scope is created.
 *
 * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The
 * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent
 * scope. This is useful when creating reusable components, which should not accidentally read or modify
 * data in the parent scope.
 *
 * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
 * directive's element. These local properties are useful for aliasing values for templates. The keys in
 * the object hash map to the name of the property on the isolate scope; the values define how the property
 * is bound to the parent scope, via matching attributes on the directive's element:
 *
 * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
 *   always a string since DOM attributes are strings. If no `attr` name is specified then the
 *   attribute name is assumed to be the same as the local name. Given `<my-component
 *   my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`,
 *   the directive's scope property `localName` will reflect the interpolated value of `hello
 *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
 *   scope. The `name` is read from the parent scope (not the directive's scope).
 *
 * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
 *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
 *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
 *   name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: {
 *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
 *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
 *   `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
 *   `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
 *   optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
 *   will be thrown upon discovering changes to the local value, since it will be impossible to sync
 *   them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
 *   method is used for tracking changes, and the equality check is based on object identity.
 *   However, if an object literal or an array literal is passed as the binding expression, the
 *   equality check is done by value (using the {@link angular.equals} function). It's also possible
 *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
 *   `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
 *
  * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an
 *   expression passed via the attribute `attr`. The expression is evaluated in the context of the
 *   parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the
 *   local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`.
 *
 *   For example, given `<my-component my-attr="parentModel">` and directive definition of
 *   `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the
 *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
 *   in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however
 *   two caveats:
 *     1. one-way binding does not copy the value from the parent to the isolate scope, it simply
 *     sets the same value. That means if your bound value is an object, changes to its properties
 *     in the isolated scope will be reflected in the parent scope (because both reference the same object).
 *     2. one-way binding watches changes to the **identity** of the parent value. That means the
 *     {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference
 *     to the value has changed. In most cases, this should not be of concern, but can be important
 *     to know if you one-way bind to an object, and then replace that object in the isolated scope.
 *     If you now change a property of the object in your parent scope, the change will not be
 *     propagated to the isolated scope, because the identity of the object on the parent scope
 *     has not changed. Instead you must assign a new object.
 *
 *   One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings
 *   back to the parent. However, it does not make this completely impossible.
 *
 * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If
 *   no `attr` name is specified then the attribute name is assumed to be the same as the local name.
 *   Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: {
 *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
 *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
 *   via an expression to the parent scope. This can be done by passing a map of local variable names
 *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
 *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
 *
 * In general it's possible to apply more than one directive to one element, but there might be limitations
 * depending on the type of scope required by the directives. The following points will help explain these limitations.
 * For simplicity only two directives are taken into account, but it is also applicable for several directives:
 *
 * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
 * * **child scope** + **no scope** =>  Both directives will share one single child scope
 * * **child scope** + **child scope** =>  Both directives will share one single child scope
 * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
 * its parent's scope
 * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
 * be applied to the same element.
 * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
 * cannot be applied to the same element.
 *
 *
 * #### `bindToController`
 * This property is used to bind scope properties directly to the controller. It can be either
 * `true` or an object hash with the same format as the `scope` property.
 *
 * When an isolate scope is used for a directive (see above), `bindToController: true` will
 * allow a component to have its properties bound to the controller, rather than to scope.
 *
 * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
 * properties. You can access these bindings once they have been initialized by providing a controller method called
 * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
 * initialized.
 *
 * <div class="alert alert-warning">
 * **Deprecation warning:** although bindings for non-ES6 class controllers are currently
 * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization
 * code that relies upon bindings inside a `$onInit` method on the controller, instead.
 * </div>
 *
 * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
 * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
 * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
 * scope (useful for component directives).
 *
 * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
 *
 *
 * #### `controller`
 * Controller constructor function. The controller is instantiated before the
 * pre-linking phase and can be accessed by other directives (see
 * `require` attribute). This allows the directives to communicate with each other and augment
 * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
 *
 * * `$scope` - Current scope associated with the element
 * * `$element` - Current element
 * * `$attrs` - Current attributes object for the element
 * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
 *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
 *    * `scope`: (optional) override the scope.
 *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
 *    * `futureParentElement` (optional):
 *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
 *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
 *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
 *          and when the `cloneLinkingFn` is passed,
 *          as those elements need to created and cloned in a special way when they are defined outside their
 *          usual containers (e.g. like `<svg>`).
 *        * See also the `directive.templateNamespace` property.
 *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
 *      then the default transclusion is provided.
 *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
 *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
 *
 * #### `require`
 * Require another directive and inject its controller as the fourth argument to the linking function. The
 * `require` property can be a string, an array or an object:
 * * a **string** containing the name of the directive to pass to the linking function
 * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
 * linking function will be an array of controllers in the same order as the names in the `require` property
 * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
 * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
 * controllers.
 *
 * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
 * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
 * have been constructed but before `$onInit` is called.
 * If the name of the required controller is the same as the local name (the key), the name can be
 * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
 * See the {@link $compileProvider#component} helper for an example of how this can be used.
 * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
 * raised (unless no link function is specified and the required controllers are not being bound to the directive
 * controller, in which case error checking is skipped). The name can be prefixed with:
 *
 * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
 * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
 * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
 * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
 * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
 *   `null` to the `link` fn if not found.
 * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
 *   `null` to the `link` fn if not found.
 *
 *
 * #### `controllerAs`
 * Identifier name for a reference to the controller in the directive's scope.
 * This allows the controller to be referenced from the directive template. This is especially
 * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
 * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
 * `controllerAs` reference might overwrite a property that already exists on the parent scope.
 *
 *
 * #### `restrict`
 * String of subset of `EACM` which restricts the directive to a specific directive
 * declaration style. If omitted, the defaults (elements and attributes) are used.
 *
 * * `E` - Element name (default): `<my-directive></my-directive>`
 * * `A` - Attribute (default): `<div my-directive="exp"></div>`
 * * `C` - Class: `<div class="my-directive: exp;"></div>`
 * * `M` - Comment: `<!-- directive: my-directive exp -->`
 *
 *
 * #### `templateNamespace`
 * String representing the document type used by the markup in the template.
 * AngularJS needs this information as those elements need to be created and cloned
 * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
 *
 * * `html` - All root nodes in the template are HTML. Root nodes may also be
 *   top-level elements such as `<svg>` or `<math>`.
 * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
 * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
 *
 * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
 *
 * #### `template`
 * HTML markup that may:
 * * Replace the contents of the directive's element (default).
 * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
 * * Wrap the contents of the directive's element (if `transclude` is true).
 *
 * Value may be:
 *
 * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
 * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
 *   function api below) and returns a string value.
 *
 *
 * #### `templateUrl`
 * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
 *
 * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
 * for later when the template has been resolved.  In the meantime it will continue to compile and link
 * sibling and parent elements as though this element had not contained any directives.
 *
 * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
 * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
 * case when only one deeply nested directive has `templateUrl`.
 *
 * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
 *
 * You can specify `templateUrl` as a string representing the URL or as a function which takes two
 * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
 * a string value representing the url.  In either case, the template URL is passed through {@link
 * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
 *
 *
 * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
 * specify what the template should replace. Defaults to `false`.
 *
 * * `true` - the template will replace the directive's element.
 * * `false` - the template will replace the contents of the directive's element.
 *
 * The replacement process migrates all of the attributes / classes from the old element to the new
 * one. See the {@link guide/directive#template-expanding-directive
 * Directives Guide} for an example.
 *
 * There are very few scenarios where element replacement is required for the application function,
 * the main one being reusable custom components that are used within SVG contexts
 * (because SVG doesn't work with custom elements in the DOM tree).
 *
 * #### `transclude`
 * Extract the contents of the element where the directive appears and make it available to the directive.
 * The contents are compiled and provided to the directive as a **transclusion function**. See the
 * {@link $compile#transclusion Transclusion} section below.
 *
 *
 * #### `compile`
 *
 * ```js
 *   function compile(tElement, tAttrs, transclude) { ... }
 * ```
 *
 * The compile function deals with transforming the template DOM. Since most directives do not do
 * template transformation, it is not used often. The compile function takes the following arguments:
 *
 *   * `tElement` - template element - The element where the directive has been declared. It is
 *     safe to do template transformation on the element and child elements only.
 *
 *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
 *     between all directive compile functions.
 *
 *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
 *
 * <div class="alert alert-warning">
 * **Note:** The template instance and the link instance may be different objects if the template has
 * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
 * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
 * should be done in a linking function rather than in a compile function.
 * </div>

 * <div class="alert alert-warning">
 * **Note:** The compile function cannot handle directives that recursively use themselves in their
 * own templates or compile functions. Compiling these directives results in an infinite loop and
 * stack overflow errors.
 *
 * This can be avoided by manually using $compile in the postLink function to imperatively compile
 * a directive's template instead of relying on automatic template compilation via `template` or
 * `templateUrl` declaration or manual compilation inside the compile function.
 * </div>
 *
 * <div class="alert alert-danger">
 * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
 *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
 *   to the link function instead.
 * </div>

 * A compile function can have a return value which can be either a function or an object.
 *
 * * returning a (post-link) function - is equivalent to registering the linking function via the
 *   `link` property of the config object when the compile function is empty.
 *
 * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
 *   control when a linking function should be called during the linking phase. See info about
 *   pre-linking and post-linking functions below.
 *
 *
 * #### `link`
 * This property is used only if the `compile` property is not defined.
 *
 * ```js
 *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
 * ```
 *
 * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
 * executed after the template has been cloned. This is where most of the directive logic will be
 * put.
 *
 *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
 *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
 *
 *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
 *     manipulate the children of the element only in `postLink` function since the children have
 *     already been linked.
 *
 *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
 *     between all directive linking functions.
 *
 *   * `controller` - the directive's required controller instance(s) - Instances are shared
 *     among all directives, which allows the directives to use the controllers as a communication
 *     channel. The exact value depends on the directive's `require` property:
 *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
 *       * `string`: the controller instance
 *       * `array`: array of controller instances
 *
 *     If a required controller cannot be found, and it is optional, the instance is `null`,
 *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
 *
 *     Note that you can also require the directive's own controller - it will be made available like
 *     any other controller.
 *
 *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
 *     This is the same as the `$transclude` parameter of directive controllers,
 *     see {@link ng.$compile#-controller- the controller section for details}.
 *     `function([scope], cloneLinkingFn, futureParentElement)`.
 *
 * #### Pre-linking function
 *
 * Executed before the child elements are linked. Not safe to do DOM transformation since the
 * compiler linking function will fail to locate the correct elements for linking.
 *
 * #### Post-linking function
 *
 * Executed after the child elements are linked.
 *
 * Note that child elements that contain `templateUrl` directives will not have been compiled
 * and linked since they are waiting for their template to load asynchronously and their own
 * compilation and linking has been suspended until that occurs.
 *
 * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
 * for their async templates to be resolved.
 *
 *
 * ### Transclusion
 *
 * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
 * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
 * scope from where they were taken.
 *
 * Transclusion is used (often with {@link ngTransclude}) to insert the
 * original contents of a directive's element into a specified place in the template of the directive.
 * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
 * content has access to the properties on the scope from which it was taken, even if the directive
 * has isolated scope.
 * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
 *
 * This makes it possible for the widget to have private state for its template, while the transcluded
 * content has access to its originating scope.
 *
 * <div class="alert alert-warning">
 * **Note:** When testing an element transclude directive you must not place the directive at the root of the
 * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
 * Testing Transclusion Directives}.
 * </div>
 *
 * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
 * directive's element, the entire element or multiple parts of the element contents:
 *
 * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
 * * `'element'` - transclude the whole of the directive's element including any directives on this
 *   element that defined at a lower priority than this directive. When used, the `template`
 *   property is ignored.
 * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
 *
 * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
 *
 * This object is a map where the keys are the name of the slot to fill and the value is an element selector
 * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
 * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
 *
 * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
 *
 * If the element selector is prefixed with a `?` then that slot is optional.
 *
 * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to
 * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
 *
 * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
 * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
 * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
 * injectable into the directive's controller.
 *
 *
 * #### Transclusion Functions
 *
 * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
 * function** to the directive's `link` function and `controller`. This transclusion function is a special
 * **linking function** that will return the compiled contents linked to a new transclusion scope.
 *
 * <div class="alert alert-info">
 * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
 * ngTransclude will deal with it for us.
 * </div>
 *
 * If you want to manually control the insertion and removal of the transcluded content in your directive
 * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
 * object that contains the compiled DOM, which is linked to the correct transclusion scope.
 *
 * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
 * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
 * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
 *
 * <div class="alert alert-info">
 * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
 * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
 * </div>
 *
 * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
 * attach function**:
 *
 * ```js
 * var transcludedContent, transclusionScope;
 *
 * $transclude(function(clone, scope) {
 *   element.append(clone);
 *   transcludedContent = clone;
 *   transclusionScope = scope;
 * });
 * ```
 *
 * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
 * associated transclusion scope:
 *
 * ```js
 * transcludedContent.remove();
 * transclusionScope.$destroy();
 * ```
 *
 * <div class="alert alert-info">
 * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
 * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
 * then you are also responsible for calling `$destroy` on the transclusion scope.
 * </div>
 *
 * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
 * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
 * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
 *
 *
 * #### Transclusion Scopes
 *
 * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
 * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
 * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
 * was taken.
 *
 * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
 * like this:
 *
 * ```html
 * <div ng-app>
 *   <div isolate>
 *     <div transclusion>
 *     </div>
 *   </div>
 * </div>
 * ```
 *
 * The `$parent` scope hierarchy will look like this:
 *
   ```
   - $rootScope
     - isolate
       - transclusion
   ```
 *
 * but the scopes will inherit prototypically from different scopes to their `$parent`.
 *
   ```
   - $rootScope
     - transclusion
   - isolate
   ```
 *
 *
 * ### Attributes
 *
 * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
 * `link()` or `compile()` functions. It has a variety of uses.
 *
 * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
 *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
 *   to the attributes.
 *
 * * *Directive inter-communication:* All directives share the same instance of the attributes
 *   object which allows the directives to use the attributes object as inter directive
 *   communication.
 *
 * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
 *   allowing other directives to read the interpolated value.
 *
 * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
 *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
 *   the only way to easily get the actual value because during the linking phase the interpolation
 *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
 *
 * ```js
 * function linkingFn(scope, elm, attrs, ctrl) {
 *   // get the attribute value
 *   console.log(attrs.ngModel);
 *
 *   // change the attribute
 *   attrs.$set('ngModel', 'new value');
 *
 *   // observe changes to interpolated attribute
 *   attrs.$observe('ngModel', function(value) {
 *     console.log('ngModel has changed value to ' + value);
 *   });
 * }
 * ```
 *
 * ## Example
 *
 * <div class="alert alert-warning">
 * **Note**: Typically directives are registered with `module.directive`. The example below is
 * to illustrate how `$compile` works.
 * </div>
 *
 <example module="compileExample" name="compile">

        $compileProvider.directive('compile', function($compile) {
          // directive factory creates a link function
          return function(scope, element, attrs) {

 *
 * @param {number} maxPriority only apply directives lower than given priority (Only effects the
 *                 root element(s), not their children)
 * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
 * (a DOM element/tree) to a scope. Where:
 *
 *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
 *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
 *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
 *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
 *  called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
 *
 *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
 *      * `scope` - is the current scope with which the linking function is working with.
 *
 *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
 *  keys may be used to control linking behavior:
 *
 *      * `parentBoundTranscludeFn` - the transclude function made available to
 *        directives; if given, it will be passed through to the link functions of
 *        directives found in `element` during compilation.
 *      * `transcludeControllers` - an object hash with keys that map controller names
 *        to a hash with the key `instance`, which maps to the controller instance;
 *        if given, it will make the controllers available to directives on the compileNode:
 *        ```
 *        {
 *          parent: {
 *            instance: parentControllerInstance
 *          }
 *        }
 *        ```
 *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
 *        the cloned elements; only needed for transcludes that are allowed to contain non html
 *        elements (e.g. SVG elements). See also the directive.controller property.
 *
 * Calling the linking function returns the element of the template. It is either the original
 * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
 *
 * After linking the view is not updated until after a call to $digest which typically is done by
 * Angular automatically.
 *
 * If you need access to the bound view, there are two ways to do it:
 *
 * - If you are not asking the linking function to clone the template, create the DOM element(s)
 *   before you send them to the compiler and keep this reference around.
 *   ```js
 *     var element = $compile('<p>{{total}}</p>')(scope);
 *   ```
 *
 * - if on the other hand, you need the element to be cloned, the view reference from the original
 *   example would not point to the clone, but rather to the original template that was cloned. In
 *   this case, you can access the clone via the cloneAttachFn:
 *   ```js
 *     var templateElement = angular.element('<p>{{total}}</p>'),
 *         scope = ....;
 *
 *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
 *       //attach the clone to DOM document at the right place
 *     });
 *
 *     //now we have reference to the cloned DOM via `clonedElement`
 *   ```
 *
 *
 * For information on how the compiler works, see the
 * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

 *
 * ### Double Compilation
 *
   Double compilation occurs when an already compiled part of the DOM gets
   compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues,
   and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it
   section on double compilation} for an in-depth explanation and ways to avoid it.

   * @description
   * Register a **component definition** with the compiler. This is a shorthand for registering a special
   * type of directive, which represents a self-contained UI component in your application. Such components
   * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
   *
   * Component definitions are very simple and do not require as much configuration as defining general
   * directives. Component definitions usually consist only of a template and a controller backing it.
   *
   * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
   * `bindToController`. They always have **isolate scope** and are restricted to elements.
   *
   * Here are a few examples of how you would usually define components:
   *
   * ```js
   *   var myMod = angular.module(...);
   *   myMod.component('myComp', {
   *     template: '<div>My name is {{$ctrl.name}}</div>',
   *     controller: function() {
   *       this.name = 'shahar';
   *     }
   *   });
   *
   *   myMod.component('myComp', {
   *     template: '<div>My name is {{$ctrl.name}}</div>',
   *     bindings: {name: '@'}
   *   });
   *
   *   myMod.component('myComp', {
   *     templateUrl: 'views/my-comp.html',
   *     controller: 'MyCtrl',
   *     controllerAs: 'ctrl',
   *     bindings: {name: '@'}
   *   });
   *
   * ```
   * For more examples, and an in-depth guide, see the {@link guide/component component guide}.
   *
   * <br />
   * See also {@link ng.$compileProvider#directive $compileProvider.directive()}.

 * @ngdoc service

 *
 * @description
 * Any uncaught exception in angular expressions is delegated to this service.
 * The default implementation simply delegates to `$log.error` which logs it into
 * the browser console.
 *
 * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
 * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
 *
 * ## Example:
 *
 * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
 * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
 * of `$log.error()`.
 *
 * ```js
 *   angular.
 *     module('exceptionOverwrite', []).
 *     factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) {
 *       return function myExceptionHandler(exception, cause) {
 *         logErrorsToBackend(exception, cause);
 *         $log.warn(exception, cause);
 *       };
 *     }]);
 * ```
 *
 * <hr />
 * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
 * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
 * (unless executed during a digest).
 *
 * If you wish, you can manually delegate exceptions, e.g.
 * `try { ... } catch(e) { $exceptionHandler(e); }`
 *
 * @param {Error} exception Exception associated with the error.
 * @param {string=} cause Optional information about the context in which

     * @description
     * The `$http` service is a core Angular service that facilitates communication with the remote
     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
     *
     * For unit testing applications that use `$http` service, see
     * {@link ngMock.$httpBackend $httpBackend mock}.
     *
     * For a higher level of abstraction, please check out the {@link ngResource.$resource
     * $resource} service.
     *
     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
     * it is important to familiarize yourself with these APIs and the guarantees they provide.
     *
     *
     * ## General usage
     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}.
     *
     * ```js
     *   // Simple GET request example:
     *   $http({
     *     method: 'GET',
     *     url: '/someUrl'
     *   }).then(function successCallback(response) {
     *       // this callback will be called asynchronously
     *       // when the response is available
     *     }, function errorCallback(response) {
     *       // called asynchronously if an error occurs
     *       // or server returns response with an error status.
     *     });
     * ```
     *
     * The response object has these properties:
     *
     *   - **data** – `{string|Object}` – The response body transformed with the transform
     *     functions.
     *   - **status** – `{number}` – HTTP status code of the response.
     *   - **headers** – `{function([headerName])}` – Header getter function.
     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
     *   - **statusText** – `{string}` – HTTP status text of the response.
     *
     * A response status code between 200 and 299 is considered a success status and will result in
     * the success callback being called. Any response status code outside of that range is
     * considered an error status and will result in the error callback being called.
     * Also, status codes less than -1 are normalized to zero. -1 usually means the request was
     * aborted, e.g. using a `config.timeout`.
     * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning
     * that the outcome (success or error) will be determined by the final response status code.
     *
     *
     * ## Shortcut methods
     *
     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
     * last argument.
     *
     * ```js
     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
     * ```
     *
     * Complete list of shortcut methods:
     *
     * - {@link ng.$http#get $http.get}
     * - {@link ng.$http#head $http.head}
     * - {@link ng.$http#post $http.post}
     * - {@link ng.$http#put $http.put}
     * - {@link ng.$http#delete $http.delete}
     * - {@link ng.$http#jsonp $http.jsonp}
     * - {@link ng.$http#patch $http.patch}
     *
     *
     * ## Writing Unit Tests that use $http
     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
     * request using trained responses.
     *
     * ```
     * $httpBackend.expectGET(...);
     * $http.get(...);
     * $httpBackend.flush();
     * ```
     *
     * ## Deprecation Notice
     * <div class="alert alert-danger">
     *   The `$http` legacy promise methods `success` and `error` have been deprecated and will be
     *   removed in v1.6.0.
     *   Use the standard `then` method instead.
     *   If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to
     *   `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.
     * </div>
     *
     * ## Setting HTTP Headers
     *
     * The $http service will automatically add certain HTTP headers to all requests. These defaults
     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
     * object, which currently contains this default configuration:
     *
     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
     *   - <code>Accept: application/json, text/plain, \*&#65279;/&#65279;\*</code>
     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
     *   - `Content-Type: application/json`
     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
     *   - `Content-Type: application/json`
     *
     * To add or overwrite these defaults, simply add or remove a property from these configuration
     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
     * with the lowercased HTTP method name as the key, e.g.
     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
     *
     * The defaults can also be set at runtime via the `$http.defaults` object in the same
     * fashion. For example:
     *
     * ```
     * module.run(function($http) {
     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
     * });
     * ```
     *
     * In addition, you can supply a `headers` property in the config object passed when
     * calling `$http(config)`, which overrides the defaults without changing them globally.
     *
     * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
     * Use the `headers` property, setting the desired header to `undefined`. For example:
     *
     * ```js
     * var req = {
     *  method: 'POST',
     *  url: 'http://example.com',
     *  headers: {
     *    'Content-Type': undefined
     *  },
     *  data: { test: 'test' }
     * }
     *
     * $http(req).then(function(){...}, function(){...});
     * ```
     *
     * ## Transforming Requests and Responses
     *
     * Both requests and responses can be transformed using transformation functions: `transformRequest`
     * and `transformResponse`. These properties can be a single function that returns
     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
     *
     * <div class="alert alert-warning">
     * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
     * function will be reflected on the scope and in any templates where the object is data-bound.
     * To prevent this, transform functions should have no side-effects.
     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
     * </div>
     *
     * ### Default Transformations
     *
     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
     * `defaults.transformResponse` properties. If a request does not provide its own transformations
     * then these will be applied.
     *
     * You can augment or replace the default transformations by modifying these properties by adding to or
     * replacing the array.
     *
     * Angular provides the following default transformations:
     *
     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
     *
     * - If the `data` property of the request configuration object contains an object, serialize it
     *   into JSON format.
     *
     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
     *
     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
     *  - If JSON response is detected, deserialize it using a JSON parser.
     *
     *
     * ### Overriding the Default Transformations Per Request
     *
     * If you wish to override the request/response transformations only for a single request then provide
     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
     * into `$http`.
     *
     * Note that if you provide these properties on the config object the default transformations will be
     * overwritten. If you wish to augment the default transformations then you must include them in your
     * local transformation array.
     *
     * The following code demonstrates adding a new response transformation to be run after the default response
     * transformations have been run.
     *
     * ```js
     * function appendTransform(defaults, transform) {
     *
     *   // We can't guarantee that the default transformation is an array
     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
     *
     *   // Append the new transformation to the defaults
     *   return defaults.concat(transform);
     * }
     *
     * $http({
     *   url: '...',
     *   method: 'GET',
     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
     *     return doTransform(value);
     *   })
     * });
     * ```
     *
     *
     * ## Caching
     *
     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
     * set the config.cache value or the default cache value to TRUE or to a cache object (created
     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
     * precedence over the default cache value.
     *
     * In order to:
     *   * cache all responses - set the default cache value to TRUE or to a cache object
     *   * cache a specific response - set config.cache value to TRUE or to a cache object
     *
     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
     * then the default `$cacheFactory("$http")` object is used.
     *
     * The default cache value can be set by updating the
     * {@link ng.$http#defaults `$http.defaults.cache`} property or the
     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
     *
     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
     * the relevant cache object. The next time the same request is made, the response is returned
     * from the cache without sending a request to the server.
     *
     * Take note that:
     *
     *   * Only GET and JSONP requests are cached.
     *   * The cache key is the request URL including search parameters; headers are not considered.
     *   * Cached responses are returned asynchronously, in the same way as responses from the server.
     *   * If multiple identical requests are made using the same cache, which is not yet populated,
     *     one request will be made to the server and remaining requests will return the same response.
     *   * A cache-control header on the response does not affect if or how responses are cached.
     *
     *
     * ## Interceptors
     *
     * Before you start creating interceptors, be sure to understand the
     * {@link ng.$q $q and deferred/promise APIs}.
     *
     * For purposes of global error handling, authentication, or any kind of synchronous or
     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
     * able to intercept requests before they are handed to the server and
     * responses before they are handed over to the application code that
     * initiated these requests. The interceptors leverage the {@link ng.$q
     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
     *
     * The interceptors are service factories that are registered with the `$httpProvider` by
     * adding them to the `$httpProvider.interceptors` array. The factory is called and
     * injected with dependencies (if specified) and returns the interceptor.
     *
     * There are two kinds of interceptors (and two kinds of rejection interceptors):
     *
     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
     *     modify the `config` object or create a new one. The function needs to return the `config`
     *     object directly, or a promise containing the `config` or a new `config` object.
     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
     *     resolved with a rejection.
     *   * `response`: interceptors get called with http `response` object. The function is free to
     *     modify the `response` object or create a new one. The function needs to return the `response`
     *     object directly, or as a promise containing the `response` or a new `response` object.
     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
     *     resolved with a rejection.
     *
     *
     * ```js
     *   // register the interceptor as a service
     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
     *     return {
     *       // optional method
     *       'request': function(config) {
     *         // do something on success
     *         return config;
     *       },
     *
     *       // optional method
     *      'requestError': function(rejection) {
     *         // do something on error
     *         if (canRecover(rejection)) {
     *           return responseOrNewPromise
     *         }
     *         return $q.reject(rejection);
     *       },
     *
     *
     *
     *       // optional method
     *       'response': function(response) {
     *         // do something on success
     *         return response;
     *       },
     *
     *       // optional method
     *      'responseError': function(rejection) {
     *         // do something on error
     *         if (canRecover(rejection)) {
     *           return responseOrNewPromise
     *         }
     *         return $q.reject(rejection);
     *       }
     *     };
     *   });
     *
     *   $httpProvider.interceptors.push('myHttpInterceptor');
     *
     *
     *   // alternatively, register the interceptor via an anonymous factory
     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
     *     return {
     *      'request': function(config) {
     *          // same as above
     *       },
     *
     *       'response': function(response) {
     *          // same as above
     *       }
     *     };
     *   });
     * ```
     *
     * ## Security Considerations
     *
     * When designing web applications, consider security threats from:
     *
     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
     *
     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
     * pre-configured with strategies that address these issues, but for this to work backend server
     * cooperation is required.
     *
     * ### JSON Vulnerability Protection
     *
     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
     * allows third party website to turn your JSON resource URL into
     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
     * Angular will automatically strip the prefix before processing it as JSON.
     *
     * For example if your server needs to return:
     * ```js
     * ['one','two']
     * ```
     *
     * which is vulnerable to attack, your server can return:
     * ```js
     * )]}',
     * ['one','two']
     * ```
     *
     * Angular will strip the prefix, before processing the JSON.
     *
     *
     * ### Cross Site Request Forgery (XSRF) Protection
     *
     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
     * which the attacker can trick an authenticated user into unknowingly executing actions on your
     * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
     * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
     * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
     * The header will not be set for cross-domain requests.
     *
     * To take advantage of this, your server needs to set a token in a JavaScript readable session
     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
     * that only JavaScript running on your domain could have sent the request. The token must be
     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
     * making up its own tokens). We recommend that the token is a digest of your site's
     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
     * for added security.
     *
     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
     * or the per-request config object.
     *
     * In order to prevent collisions in environments where multiple Angular apps share the
     * same domain or subdomain, we recommend that each application uses unique cookie name.
     *
     * @param {object} config Object describing the request to be made and how it should be
     *    processed. The object has following properties:
     *
     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
     *      with the `paramSerializer` and appended as GET parameters.
     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
     *      HTTP headers to send to the server. If the return value of a function is null, the
     *      header will not be sent. Functions accept a config object as an argument.
     *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
     *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
     *      The handler will be called in the context of a `$apply` block.
     *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
     *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
     *      The handler will be called in the context of a `$apply` block.
     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
     *    - **transformRequest** –
     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
     *      transform function or an array of such functions. The transform function takes the http
     *      request body and headers and returns its transformed (typically serialized) version.
     *      See {@link ng.$http#overriding-the-default-transformations-per-request
     *      Overriding the Default Transformations}
     *    - **transformResponse** –
     *      `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
     *      transform function or an array of such functions. The transform function takes the http
     *      response body, headers and status and returns its transformed (typically deserialized) version.
     *      See {@link ng.$http#overriding-the-default-transformations-per-request
     *      Overriding the Default Transformations}
     *    - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
     *      prepare the string representation of request parameters (specified as an object).
     *      If specified as string, it is interpreted as function registered with the
     *      {@link $injector $injector}, which means you can create your own serializer
     *      by registering it as a {@link auto.$provide#service service}.
     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
     *    - **cache** – `{boolean|Object}` – A boolean value or object created with
     *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
     *      See {@link $http#caching $http Caching} for more information.
     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
     *      that should abort the request when resolved.
     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
     *      for more information.
     *    - **responseType** - `{string}` - see
     *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
     *
     * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
     *                        when the request succeeds or fails.
     *
     *
     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
     *   requests. This is primarily meant to be used for debugging purposes.

     * @ngdoc service
     * @name $interpolate
     * @kind function
     *
     * @requires $parse
     * @requires $sce
     *
     * @description
     *
     * Compiles a string with markup into an interpolation function. This service is used by the
     * HTML {@link ng.$compile $compile} service for data binding. See
     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
     * interpolation markup.
     *
     *
     * ```js
     *   var $interpolate = ...; // injected
     *   var exp = $interpolate('Hello {{name | uppercase}}!');
     *   expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
     * ```
     *
     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
     * `true`, the interpolation function will return `undefined` unless all embedded expressions
     * evaluate to a value other than `undefined`.
     *
     * ```js
     *   var $interpolate = ...; // injected
     *   var context = {greeting: 'Hello', name: undefined };
     *
     *   // default "forgiving" mode
     *   var exp = $interpolate('{{greeting}} {{name}}!');
     *   expect(exp(context)).toEqual('Hello !');
     *
     *   // "allOrNothing" mode
     *   exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
     *   expect(exp(context)).toBeUndefined();
     *   context.name = 'Angular';
     *   expect(exp(context)).toEqual('Hello Angular!');
     * ```
     *
     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
     *
     * #### Escaped Interpolation
     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
     * or binding.
     *
     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
     * degree, while also enabling code examples to work without relying on the
     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
     *
     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all
     * interpolation start/end markers with their escaped counterparts.**
     *
     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
     * output when the $interpolate service processes the text. So, for HTML elements interpolated
     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
     * this is typically useful only when user-data is used in rendering a template from the server, or
     * when otherwise untrusted data is used by a directive.
     *
     * <example name="interpolation">
     *  <file name="index.html">
     *    <div ng-init="username='A user'">
     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
     *        </p>
     *      <p><strong>{{username}}</strong> attempts to inject code which will deface the
     *        application, but fails to accomplish their task, because the server has correctly
     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
     *        characters.</p>
     *      <p>Instead, the result of the attempted script injection is visible, and can be removed
     *        from the database by an administrator.</p>
     *    </div>
     *  </file>
     * </example>
     *
     * @knownIssue
     * It is currently not possible for an interpolated expression to contain the interpolation end
     * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
     * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
     *
     * @knownIssue
     * All directives and components must use the standard `{{` `}}` interpolation symbols
     * in their templates. If you change the application interpolation symbols the {@link $compile}
     * service will attempt to denormalize the standard symbols to the custom symbols.
     * The denormalization process is not clever enough to know not to replace instances of the standard
     * symbols where they would not normally be treated as interpolation symbols. For example in the following
     * code snippet the closing braces of the literal object will get incorrectly denormalized:
     *
     * ```
     * <div data-context='{"context":{"id":3,"type":"page"}}">
     * ```
     *
     * The workaround is to ensure that such instances are separated by whitespace:
     * ```
     * <div data-context='{"context":{"id":3,"type":"page"} }">
     * ```
     *
     * See https://github.com/angular/angular.js/pull/14610#issuecomment-219401099 for more information.

      * @description
      * Angular's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
      * milliseconds.
      *
      * The return value of registering an interval function is a promise. This promise will be
      * notified upon each tick of the interval, and will be resolved after `count` iterations, or
      * run indefinitely if `count` is not defined. The value of the notification will be the
      * number of iterations that have run.
      * To cancel an interval, call `$interval.cancel(promise)`.
      *
      * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
      * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
      * time.
      *
      * <div class="alert alert-warning">
      * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
      * with them.  In particular they are not automatically destroyed when a controller's scope or a
      * directive's element are destroyed.
      * You should take this into consideration and make sure to always cancel the interval at the
      * appropriate moment.  See the example below for more details on how and when to do this.
      * </div>
      *
      * @param {function()} fn A function that should be called repeatedly. If no additional arguments
      *   are passed (see below), the function is called with the current iteration count.
      * @param {number} delay Number of milliseconds between each function call.
      * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
      *   indefinitely.
      * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
      *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
      * @param {...*=} Pass additional parameters to the executed function.

 * @description
 * The $location service parses the URL in the browser address bar (based on the
 * [window.location](https://developer.mozilla.org/en/window.location)) and makes the URL
 * available to your application. Changes to the URL in the address bar are reflected into
 * $location service and changes to $location are reflected into the browser address bar.
 *
 * **The $location service:**
 *
 * - Exposes the current URL in the browser address bar, so you can
 *   - Watch and observe the URL.
 *   - Change the URL.
 * - Synchronizes the URL with the browser when the user
 *   - Changes the address bar.
 *   - Clicks the back or forward button (or clicks a History link).
 *   - Clicks on a link.
 * - Represents the URL object as a set of methods (protocol, host, port, path, search, hash).

// Sandboxing Angular Expressions
// ------------------------------
// Angular expressions are generally considered safe because these expressions only have direct
// access to `$scope` and locals. However, one can obtain the ability to execute arbitrary JS code by
// obtaining a reference to native JS functions such as the Function constructor.
//
// As an example, consider the following Angular expression:
//
//   {}.toString.constructor('alert("evil JS code")')
//
// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
// against the expression language, but not to prevent exploits that were enabled by exposing
// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
// practice and therefore we are not even trying to protect against interaction with an object
// explicitly exposed in this way.
//
// In general, it is not possible to access a Window object from an angular expression unless a
// window or some DOM object that has a reference to window is published onto a Scope.
// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
// native objects.
//

  * @name $parseProvider#setIdentifierFns
  *
  * @description
  *
  * Allows defining the set of characters that are allowed in Angular expressions. The function
  * `identifierStart` will get called to know if a given character is a valid character to be the
  * first character for an identifier. The function `identifierContinue` will get called to know if
  * a given character is a valid character to be a follow-up identifier character. The functions
  * `identifierStart` and `identifierContinue` will receive as arguments the single character to be
  * identifier and the character code point. These arguments will be `string` and `numeric`. Keep in
  * mind that the `string` parameter can be two characters long depending on the character
  * representation. It is expected for the function to return `true` or `false`, whether that
  * character is allowed or not.
  *
  * Since this function will be called extensively, keep the implementation of these functions fast,
  * as the performance of these functions have a direct impact on the expressions parsing speed.
  *
  * @param {function=} identifierStart The function that will decide whether the given character is
  *   a valid identifier start character.
  * @param {function=} identifierContinue The function that will decide whether the given character is
  *   a valid identifier continue character.

/**
 * @ngdoc service
 * @name $q
 * @requires $rootScope
 * @this
 *
 * @description
 * A service that helps you run functions asynchronously, and use their return values (or exceptions)
 * when they are done processing.
 *
 * This is an implementation of promises/deferred objects inspired by
 * [Kris Kowal's Q](https://github.com/kriskowal/q).
 *
 * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
 * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
 *
 * # $q constructor
 *
 * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
 * function as the first argument. This is similar to the native Promise implementation from ES6,
 * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
 *
 * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
 * available yet.
 *
 * It can be used like so:
 *
 * ```js
 *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
 *   // are available in the current lexical scope (they could have been injected or passed in).
 *
 *   function asyncGreet(name) {
 *     // perform some asynchronous operation, resolve or reject the promise when appropriate.
 *     return $q(function(resolve, reject) {
 *       setTimeout(function() {
 *         if (okToGreet(name)) {
 *           resolve('Hello, ' + name + '!');
 *         } else {
 *           reject('Greeting ' + name + ' is not allowed.');
 *         }
 *       }, 1000);
 *     });
 *   }
 *
 *   var promise = asyncGreet('Robin Hood');
 *   promise.then(function(greeting) {
 *     alert('Success: ' + greeting);
 *   }, function(reason) {
 *     alert('Failed: ' + reason);
 *   });
 * ```
 *
 * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
 *
 * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
 *
 * However, the more traditional CommonJS-style usage is still available, and documented below.
 *
 * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
 * interface for interacting with an object that represents the result of an action that is
 * performed asynchronously, and may or may not be finished at any given point in time.
 *
 * From the perspective of dealing with error handling, deferred and promise APIs are to
 * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
 *
 * ```js
 *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
 *   // are available in the current lexical scope (they could have been injected or passed in).
 *
 *   function asyncGreet(name) {
 *     var deferred = $q.defer();
 *
 *     setTimeout(function() {
 *       deferred.notify('About to greet ' + name + '.');
 *
 *       if (okToGreet(name)) {
 *         deferred.resolve('Hello, ' + name + '!');
 *       } else {
 *         deferred.reject('Greeting ' + name + ' is not allowed.');
 *       }
 *     }, 1000);
 *
 *     return deferred.promise;
 *   }
 *
 *   var promise = asyncGreet('Robin Hood');
 *   promise.then(function(greeting) {
 *     alert('Success: ' + greeting);
 *   }, function(reason) {
 *     alert('Failed: ' + reason);
 *   }, function(update) {
 *     alert('Got notification: ' + update);
 *   });
 * ```
 *
 * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
 * comes in the way of guarantees that promise and deferred APIs make, see
 * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
 *
 * Additionally the promise api allows for composition that is very hard to do with the
 * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
 * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
 * section on serial or parallel joining of promises.
 *
 * # The Deferred API
 *
 * A new instance of deferred is constructed by calling `$q.defer()`.
 *
 * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
 * that can be used for signaling the successful or unsuccessful completion, as well as the status
 * of the task.
 *
 * **Methods**
 *
 * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
 *   constructed via `$q.reject`, the promise will be rejected instead.
 * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
 *   resolving it with a rejection constructed via `$q.reject`.
 * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
 *   multiple times before the promise is either resolved or rejected.
 *
 * **Properties**
 *
 * - promise – `{Promise}` – promise object associated with this deferred.
 *
 *
 * # The Promise API
 *
 * A new promise instance is created when a deferred instance is created and can be retrieved by
 * calling `deferred.promise`.
 *
 * The purpose of the promise object is to allow for interested parties to get access to the result
 * of the deferred task when it completes.
 *
 * **Methods**
 *
 * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
 *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
 *   as soon as the result is available. The callbacks are called with a single argument: the result
 *   or rejection reason. Additionally, the notify callback may be called zero or more times to
 *   provide a progress indication, before the promise is resolved or rejected.
 *
 *   This method *returns a new promise* which is resolved or rejected via the return value of the
 *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
 *   with the value which is resolved in that promise using
 *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
 *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
 *   resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
 *   arguments are optional.
 *
 * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
 *
 * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
 *   but to do so without modifying the final value. This is useful to release resources or do some
 *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
 *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
 *   more information.
 *
 * # Chaining promises
 *
 * Because calling the `then` method of a promise returns a new derived promise, it is easily
 * possible to create a chain of promises:
 *
 * ```js
 *   promiseB = promiseA.then(function(result) {
 *     return result + 1;
 *   });
 *
 *   // promiseB will be resolved immediately after promiseA is resolved and its value
 *   // will be the result of promiseA incremented by 1
 * ```
 *
 * It is possible to create chains of any length and since a promise can be resolved with another
 * promise (which will defer its resolution further), it is possible to pause/defer resolution of
 * the promises at any point in the chain. This makes it possible to implement powerful APIs like
 * $http's response interceptors.
 *
 *
 * # Differences between Kris Kowal's Q and $q
 *
 *  There are two main differences:
 *
 * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
 *   mechanism in angular, which means faster propagation of resolution or rejection into your
 *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
 * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
 *   all the important functionality needed for common async tasks.
 *
 * # Testing
 *
 *  ```js
 *    it('should simulate promise', inject(function($q, $rootScope) {
 *      var deferred = $q.defer();
 *      var promise = deferred.promise;
 *      var resolvedValue;
 *
 *      promise.then(function(value) { resolvedValue = value; });
 *      expect(resolvedValue).toBeUndefined();
 *
 *      // Simulate resolving of promise
 *      deferred.resolve(123);
 *      // Note that the 'then' function does not get called synchronously.
 *      // This is because we want the promise API to always be async, whether or not
 *      // it got called synchronously or asynchronously.
 *      expect(resolvedValue).toBeUndefined();
 *
 *      // Propagate promise resolution to 'then' functions using $apply().
 *      $rootScope.$apply();
 *      expect(resolvedValue).toEqual(123);
 *    }));
 *  ```
 *
 * @param {function(function, function)} resolver Function which is responsible for resolving or
 *   rejecting the newly created promise. The first parameter is a function which resolves the
 *   promise, the second parameter is a function which rejects the promise.
 *
 * @returns {Promise} The newly created promise.

   * `reject` as the `throw` keyword in JavaScript. This also means that if you "catch" an error via
   * a promise error callback and you want to forward the error to the promise derived from the
   * current promise, you have to "rethrow" the error by returning a rejection constructed via
   * `reject`.
   *
   * ```js
   *   promiseB = promiseA.then(function(result) {
   *     // success: do something and resolve promiseB
   *     //          with the old or a new result
   *     return result;
   *   }, function(reason) {
   *     // error: handle the error if possible and
   *     //        resolve promiseB with newPromiseOrValue,
   *     //        otherwise forward the rejection to promiseB
   *     if (canHandle(reason)) {

/**
 * DESIGN NOTES
 *
 * The design decisions behind the scope are heavily favored for speed and memory consumption.
 *
 * The typical use of scope is to watch the expressions, which most of the time return the same
 * value as last time so we optimize the operation.
 *
 * Closures construction is expensive in terms of speed as well as memory:
 *   - No closures, instead use prototypical inheritance for API
 *   - Internal state needs to be stored on scope directly, which means that private state is
 *     exposed as $$____ properties
 *
 * Loop operations are optimized by using while(count--) { ... }
 *   - This means that in order to keep the same order of execution as addition we have to add
 *     items to the array at the beginning (unshift) instead of at the end (push)
 *
 * Child scopes are created and removed often
 *   - Using an array would be slow since inserts in the middle are expensive; so we use linked lists
 *
 * There are fewer watches than observers. This is why you don't want the observer to be implemented
 * in the same way as watch. Watch requires return of the initialization function which is expensive
 * to construct.

       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.

       *
       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
       * watcher. In rare cases, this is undesirable because the listener is called when the result
       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
       * listener was called due to initialization.

       * @description
       * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
       * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
       * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
       * until no more listeners are firing. This means that it is possible to get into an infinite
       * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
       * iterations exceeds 10.
       *
       * Usually, you don't call `$digest()` directly in
       * {@link ng.directive:ngController controllers} or in
       * {@link ng.$compileProvider#directive directives}.
       * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
       * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
       *
       * If you want to be notified whenever `$digest()` is called,
       * you can register a `watchExpression` function with
       * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
       *
       * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
       *
       * # Example
       * ```js
           var scope = ...;
           scope.name = 'misko';
           scope.counter = 0;

           expect(scope.counter).toEqual(0);

 * @description
 *
 * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
 * Contextual Escaping (SCE)} services to AngularJS.
 *
 * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
 * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS.  This is
 * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
 * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
 * work because `$sce` delegates to `$sceDelegate` for these operations.
 *
 * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
 *
 * The default instance of `$sceDelegate` should work out of the box with little pain.  While you
 * can override it completely to change the behavior of `$sce`, the common case would
 * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
 * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
 * templates.  Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist
 * $sceDelegateProvider.resourceUrlWhitelist} and {@link

 * The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate
 * $sceDelegate} service.  This allows one to get/set the whitelists and blacklists used to ensure
 * that the URLs used for sourcing Angular templates are safe.  Refer {@link
 * ng.$sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider.resourceUrlWhitelist} and
 * {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}
 *
 * For the general details about this service in Angular, read the main page for {@link ng.$sce
 * Strict Contextual Escaping (SCE)}.
 *
 * **Example**:  Consider the following case. <a name="example"></a>
 *
 * - your app is hosted at url `http://myapp.example.com/`
 * - but some of your templates are hosted on other domains you control such as
 *   `http://srv01.assets.example.com/`, `http://srv02.assets.example.com/`, etc.
 * - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
 *
 * Here is what a secure configuration for this scenario might look like:
 *
 * ```
 *  angular.module('myApp', []).config(function($sceDelegateProvider) {
 *    $sceDelegateProvider.resourceUrlWhitelist([
 *      // Allow same origin resource loads.
 *      'self',
 *      // Allow loading from our assets domain.  Notice the difference between * and **.
 *      'http://srv*.assets.example.com/**'

 *
 *    // The blacklist overrides the whitelist so the open redirect here is blocked.

/**
 * @ngdoc service
 * @name $sce
 * @kind function
 *
 * @description
 *
 * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
 *
 * # Strict Contextual Escaping
 *
 * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
 * contexts to result in a value that is marked as safe to use for that context.  One example of
 * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
 * to these contexts as privileged or SCE contexts.
 *
 * As of version 1.2, Angular ships with SCE enabled by default.
 *
 * Note:  When enabled (the default), IE<11 in quirks mode is not supported.  In this mode, IE<11 allow
 * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
 * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
 * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
 * to the top of your HTML document.
 *
 * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for
 * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
 *
 * Here's an example of a binding in a privileged context:
 *
 * ```
 * <input ng-model="userHtml" aria-label="User input">
 * <div ng-bind-html="userHtml"></div>
 * ```
 *
 * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
 * disabled, this application allows the user to render arbitrary HTML into the DIV.
 * In a more realistic example, one may be rendering user comments, blog articles, etc. via
 * bindings.  (HTML is just one example of a context where rendering user controlled input creates
 * security vulnerabilities.)
 *
 * For the case of HTML, you might use a library, either on the client side, or on the server side,
 * to sanitize unsafe HTML before binding to the value and rendering it in the document.
 *
 * How would you ensure that every place that used these types of bindings was bound to a value that
 * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
 * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
 * properties/fields and forgot to update the binding to the sanitized value?
 *
 * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
 * determine that something explicitly says it's safe to use a value for binding in that
 * context.  You can then audit your code (a simple grep would do) to ensure that this is only done
 * for those values that you can easily tell are safe - because they were received from your server,
 * sanitized by your library, etc.  You can organize your codebase to help with this - perhaps
 * allowing only the files in a specific directory to do this.  Ensuring that the internal API
 * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
 *
 * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
 * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
 * obtain values that will be accepted by SCE / privileged contexts.
 *
 *
 * ## How does it work?
 *
 * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
 * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link
 * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
 * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
 *
 * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
 * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
 * simplified):
 *
 * ```
 * var ngBindHtmlDirective = ['$sce', function($sce) {
 *   return function(scope, element, attr) {
 *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
 *       element.html(value || '');
 *     });
 *   };
 * }];
 * ```
 *
 * ## Impact on loading templates
 *
 * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
 * `templateUrl`'s specified by {@link guide/directive directives}.
 *
 * By default, Angular only loads templates from the same domain and protocol as the application
 * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
 * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
 * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
 * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
 *
 * *Please note*:
 * The browser's
 * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
 * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
 * policy apply in addition to this and may further restrict whether the template is successfully
 * loaded.  This means that without the right CORS policy, loading templates from a different domain
 * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
 * browsers.
 *
 * ## This feels like too much overhead
 *
 * It's important to remember that SCE only applies to interpolation expressions.
 *
 * If your expressions are constant literals, they're automatically trusted and you don't need to
 * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
 * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
 *
 * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
 * through {@link ng.$sce#getTrusted $sce.getTrusted}.  SCE doesn't play a role here.
 *
 * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
 * templates in `ng-include` from your application's domain without having to even know about SCE.
 * It blocks loading templates from other domains or loading templates over http from an https
 * served document.  You can change these by setting your own custom {@link
 * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
 * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
 *
 * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
 * application that's secure and can be audited to verify that with much more ease than bolting
 * security onto an application later.
 *
 * <a name="contexts"></a>
 * ## What trusted context types are supported?
 *
 * | Context             | Notes          |
 * |---------------------|----------------|
 * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
 * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
 * | `$sce.URL`          | For URLs that are safe to follow as links.  Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. |
 * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG`, `VIDEO`, `AUDIO`, `SOURCE`, and `TRACK` (e.g. `IFRAME`, `OBJECT`, etc.)  <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
 * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
 *
 * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
 *
 *  Each element in these arrays must be one of the following:
 *
 *  - **'self'**
 *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
 *      domain** as the application document using the **same protocol**.
 *  - **String** (except the special value `'self'`)
 *    - The string is matched against the full *normalized / absolute URL* of the resource
 *      being tested (substring matches are not good enough.)
 *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
 *      match themselves.
 *    - `*`: matches zero or more occurrences of any character other than one of the following 6
 *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
 *      in a whitelist.
 *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
 *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
 *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
 *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
 *      http://foo.example.com/templates/**).
 *  - **RegExp** (*see caveat below*)
 *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
 *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
 *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
 *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
 *      small number of cases.  A `.` character in the regex used when matching the scheme or a
 *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
 *      is highly recommended to use the string patterns and only fall back to regular expressions
 *      as a last resort.
 *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
 *      matched against the **entire** *normalized / absolute URL* of the resource being tested
 *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
 *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
 *    - If you are generating your JavaScript from some other templating engine (not
 *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
 *      remember to escape your regular expression (and be aware that you might need more than
 *      one level of escaping depending on your templating engine and the way you interpolated
 *      the value.)  Do make use of your platform's escaping mechanism as it might be good
 *      enough before coding your own.  E.g. Ruby has
 *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
 *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
 *      Javascript lacks a similar built in function for escaping.  Take a look at Google
 *      Closure library's [goog.string.regExpEscape(s)](
 *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
 *
 * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

 *
 * ## Can I disable SCE completely?
 *
 * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
 * for little coding overhead.  It will be much harder to take an SCE disabled application and
 * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
 * for cases where you have a lot of existing code that was written before SCE was introduced and
 * you're migrating them a module at a time.
 *
 * That said, here's how you can completely disable SCE:
 *
 * ```
 * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
 *   // Completely disable SCE.  For demonstration purposes only!
 *   // Do not use in new projects.
 *   $sceProvider.enabled(false);
 * });
 * ```
 *

  /* Design notes on the default implementation for SCE.
   *
   * The API contract for the SCE delegate
   * -------------------------------------
   * The SCE delegate object must provide the following 3 methods:
   *
   * - trustAs(contextEnum, value)
   *     This method is used to tell the SCE service that the provided value is OK to use in the
   *     contexts specified by contextEnum.  It must return an object that will be accepted by
   *     getTrusted() for a compatible contextEnum and return this value.
   *
   * - valueOf(value)
   *     For values that were not produced by trustAs(), return them as is.  For values that were
   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
   *     such a value.
   *
   * - getTrusted(contextEnum, value)
   *     This function should return the a value that is safe to use in the context specified by
   *     contextEnum or throw and exception otherwise.
   *
   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
   * instance, an implementation could maintain a registry of all trusted objects by context.  In
   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
   * return the same object passed in if it was found in the registry under a compatible context or
   * throw an exception otherwise.  An implementation might only wrap values some of the time based
   * on some criteria.  getTrusted() might return a value and not throw an exception for special
   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
   *
   *
   * A note on the inheritance model for SCE contexts
   * ------------------------------------------------
   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
   * is purely an implementation details.
   *
   * The contract is simply this:
   *
   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
   *     will also succeed.
   *
   * Inheritance happens to capture this in a natural way.  In some future, we
   * may not use inheritance anymore.  That is OK because no code outside of
   * sce.js and sceSpecs.js would need to be aware of this detail.

/**
 *
 * Implementation Notes for non-IE browsers
 * ----------------------------------------
 * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
 * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
 * URL will be resolved into an absolute URL in the context of the application document.
 * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
 * properties are all populated to reflect the normalized URL.  This approach has wide
 * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
 * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
 *
 * Implementation Notes for IE
 * ---------------------------
 * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
 * browsers.  However, the parsed components will not be set if the URL assigned did not specify
 * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
 * work around that by performing the parsing in a 2nd step by taking a previously normalized
 * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
 * properties such as protocol, hostname, port, etc.

/**
 * @ngdoc filter
 * @name filter
 * @kind function
 *
 * @description
 * Selects a subset of items from `array` and returns it as a new array.
 *
 * @param {Array} array The source array.
 * @param {string|Object|function()} expression The predicate to be used for selecting items from
 *   `array`.
 *
 *   Can be one of:
 *
 *   - `string`: The string is used for matching against the contents of the `array`. All strings or
 *     objects with string properties in `array` that match this string will be returned. This also
 *     applies to nested object properties.
 *     The predicate can be negated by prefixing the string with `!`.
 *
 *   - `Object`: A pattern object can be used to filter specific properties on objects contained
 *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
 *     which have property `name` containing "M" and property `phone` containing "1". A special
 *     property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
 *     against any property of the object or its nested object properties. That's equivalent to the
 *     simple substring match with a `string` as described above. The special property name can be
 *     overwritten, using the `anyPropertyKey` parameter.
 *     The predicate can be negated by prefixing the string with `!`.
 *     For example `{name: "!M"}` predicate will return an array of items which have property `name`
 *     not containing "M".
 *
 *     Note that a named property will match properties on the same level only, while the special
 *     `$` property will match properties on the same level or deeper. E.g. an array item like
 *     `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
 *     **will** be matched by `{$: 'John'}`.
 *
 *   - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
 *     The function is called for each element of the array, with the element, its index, and
 *     the entire array itself as arguments.
 *
 *     The final result is an array of those elements that the predicate returned true for.
 *
 * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
 *     determining if the expected value (from the filter expression) and actual value (from
 *     the object in the array) should be considered a match.
 *
 *   Can be one of:
 *
 *   - `function(actual, expected)`:
 *     The function will be given the object value and the predicate value to compare and
 *     should return true if both values should be considered equal.
 *
 *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
 *     This is essentially strict comparison of expected and actual.
 *
 *   - `false`: A short hand for a function which will look for a substring match in a case
 *     insensitive way. Primitive values are converted to strings. Objects are not compared against
 *     primitives, unless they have a custom `toString` method (e.g. `Date` objects).
 *
 *
 *   Defaults to `false`.
 *
 * @param {string} [anyPropertyKey] The special property name that matches against any property.
 *     By default `$`.

 *
 *   `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
 *   `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
 *   (e.g. `"h 'o''clock'"`).

 *    specified in the string input, the time is considered to be in the local timezone.
 * @param {string=} format Formatting rules (see Description). If not specified,
 *    `mediumDate` is used.
 * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the

 * @description
 * Creates a new array or string containing only a specified number of elements. The elements are
 * taken from either the beginning or the end of the source array, string or number, as specified by
 * the value and sign (positive or negative) of `limit`. Other array-like objects are also supported
 * (e.g. array subclasses, NodeLists, jqLite/jQuery collections etc). If a number is used as input,
 * it is converted to a string.
 *
 * @param {Array|ArrayLike|string|number} input - Array/array-like, string or number to be limited.
 * @param {string|number} limit - The length of the returned array or string. If the `limit` number
 *     is positive, `limit` number of items from the beginning of the source array/string are copied.
 *     If the number is negative, `limit` number  of items from the end of the source array/string
 *     are copied. The `limit` will be trimmed if it exceeds `array.length`. If `limit` is undefined,
 *     the input will be returned unchanged.
 * @param {(string|number)=} begin - Index at which to begin limitation. As a negative index,
 *     `begin` indicates an offset from the end of `input`. Defaults to `0`.
 * @returns {Array|string} A new sub-array or substring of length `limit` or less if the input had
 *     less than `limit` elements.

/**
 * @ngdoc filter
 * @name orderBy
 * @kind function
 *
 * @description
 * Returns an array containing the items from the specified `collection`, ordered by a `comparator`
 * function based on the values computed using the `expression` predicate.
 *
 * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
 * `[{id: 'bar'}, {id: 'foo'}]`.
 *
 * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
 * String, etc).
 *
 * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
 * for the preceding one. The `expression` is evaluated against each item and the output is used
 * for comparing with other items.
 *
 * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
 * ascending order.
 *
 * The comparison is done using the `comparator` function. If none is specified, a default, built-in
 * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
 * strings alphabetically).
 *
 * ### Under the hood
 *
 * Ordering the specified `collection` happens in two phases:
 *
 * 1. All items are passed through the predicate (or predicates), and the returned values are saved
 *    along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
 *    through a predicate that extracts the value of the `label` property, would be transformed to:
 *    ```
 *    {
 *      value: 'foo',
 *      type: 'string',
 *      index: ...
 *    }
 *    ```
 * 2. The comparator function is used to sort the items, based on the derived values, types and
 *    indices.
 *
 * If you use a custom comparator, it will be called with pairs of objects of the form
 * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
 * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
 * second, or `1` otherwise.
 *
 * In order to ensure that the sorting will be deterministic across platforms, if none of the
 * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
 * dummy predicate that returns the item's index as `value`.
 * (If you are using a custom comparator, make sure it can handle this predicate as well.)
 *
 * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
 * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
 * it to the comparator. The following rules govern the conversion:
 *
 * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
 *    used instead.<br />
 *    (If the object has a `valueOf()` method that returns another object, then the returned object
 *    will be used in subsequent steps.)
 * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
 *    returns a primitive, its return value will be used instead.<br />
 *    (If the object has a `toString()` method that returns another object, then the returned object
 *    will be used in subsequent steps.)
 * 3. No conversion; the object itself is used.
 *
 * ### The default comparator
 *
 * The default, built-in comparator should be sufficient for most usecases. In short, it compares
 * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
 * using their index in the original collection, and sorts values of different types by type.
 *
 * More specifically, it follows these steps to determine the relative order of items:
 *
 * 1. If the compared values are of different types, compare the types themselves alphabetically.
 * 2. If both values are of type `string`, compare them alphabetically in a case- and
 *    locale-insensitive way.
 * 3. If both values are objects, compare their indices instead.
 * 4. Otherwise, return:
 *    -  `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
 *    - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
 *    -  `1`, otherwise.
 *
 * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
 *           saved as numbers and not strings.
 * **Note:** For the purpose of sorting, `null` values are treated as the string `'null'` (i.e.
 *           `type: 'string'`, `value: 'null'`). This may cause unexpected sort order relative to
 *           other values.
 *
 * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
 * @param {(Function|string|Array.<Function|string>)=} expression - A predicate (or list of
 *    predicates) to be used by the comparator to determine the order of elements.
 *
 *    Can be one of:
 *
 *    - `Function`: A getter function. This function will be called with each item as argument and
 *      the return value will be used for sorting.
 *    - `string`: An Angular expression. This expression will be evaluated against each item and the
 *      result will be used for sorting. For example, use `'label'` to sort by a property called
 *      `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
 *      property.<br />
 *      (The result of a constant expression is interpreted as a property name to be used for
 *      comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
 *      property called `special name`.)<br />
 *      An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
 *      ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
 *      (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
 *    - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
 *      relative order of two items, the next predicate is used as a tie-breaker.
 *
 * **Note:** If the predicate is missing or empty then it defaults to `'+'`.
 *
 * @param {boolean=} reverse - If `true`, reverse the sorting order.
 * @param {(Function)=} comparator - The comparator function used to determine the relative order of
 *    value pairs. If omitted, the built-in comparator will be used.
 *
 * @returns {Array} - The sorted array.
 *
 *
 * @example
 * ### Ordering a table with `ngRepeat`
 *
 * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
 * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
 * it defaults to the built-in comparator.

 * ### Using a custom comparator
 *
 * If you have very specific requirements about the way items are sorted, you can pass your own
 * comparator function. For example, you might need to compare some strings in a locale-sensitive
 * way. (When specifying a custom comparator, you also need to pass a value for the `reverse`
 * argument - passing `false` retains the default sorting order, i.e. ascending.)

   * is not an issue with normal use, as freshly compiled and linked controls are in a `$pristine`
   * state.
   *
   * However, if the method is used programmatically, for example by adding dynamically created controls,
   * or controls that have been previously removed without destroying their corresponding DOM element,
   * it's the developers responsibility to make sure the current state propagates to the parent form.
   *
   * For example, if an input control is added that is already `$dirty` and has `$error` properties,
   * calling `$setDirty()` and `$validate()` afterwards will propagate the state to the parent form.

 /**
 * @ngdoc directive
 * @name form
 * @restrict E
 *
 * @description
 * Directive that instantiates
 * {@link form.FormController FormController}.
 *
 * If the `name` attribute is specified, the form controller is published onto the current scope under
 * this name.
 *
 * # Alias: {@link ng.directive:ngForm `ngForm`}
 *
 * In Angular, forms can be nested. This means that the outer form is valid when all of the child
 * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
 * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
 * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
 * of controls needs to be determined.
 *
 * # CSS classes
 *  - `ng-valid` is set if the form is valid.
 *  - `ng-invalid` is set if the form is invalid.
 *  - `ng-pending` is set if the form is pending.
 *  - `ng-pristine` is set if the form is pristine.
 *  - `ng-dirty` is set if the form is dirty.
 *  - `ng-submitted` is set if the form was submitted.
 *
 * Keep in mind that ngAnimate can detect each of these classes when added and removed.
 *
 *
 * # Submitting a form and preventing the default action
 *
 * Since the role of forms in client-side Angular applications is different than in classical
 * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
 * page reload that sends the data to the server. Instead some javascript logic should be triggered
 * to handle the form submission in an application-specific way.
 *
 * For this reason, Angular prevents the default action (form submission to the server) unless the
 * `<form>` element has an `action` attribute specified.
 *
 * You can use one of the following two ways to specify what javascript method should be called when
 * a form is submitted:
 *
 * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
 * - {@link ng.directive:ngClick ngClick} directive on the first
  *  button or input field of type submit (input[type=submit])
 *
 * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
 * or {@link ng.directive:ngClick ngClick} directives.
 * This is because of the following form submission rules in the HTML specification:
 *
 * - If a form has only one input field then hitting enter in this field triggers form submit
 * (`ngSubmit`)
 * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
 * doesn't trigger submit
 * - if a form has one or more input fields and one or more buttons or input[type=submit] then
 * hitting enter in any of the input fields will trigger the click handler on the *first* button or
 * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
 *
 * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
 * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
 * to have access to the updated model.
 *
 * ## Animation Hooks
 *
 * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
 * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
 * other validations that are performed within the form. Animations in ngForm are similar to how
 * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
 * as JS animations.
 *
 * The following example shows a simple way to utilize CSS transitions to style a form element
 * that has been rendered as invalid after it has been validated:
 *
 * <pre>
 * //be sure to include ngAnimate as a module to hook into more
 * //advanced animations
 * .my-form {
 *   transition:0.5s linear all;
 *   background: white;
 * }
 * .my-form.ng-invalid {
 *   background: red;
 *   color:white;
 * }
 * </pre>
 *
 * @example
    <example name="ng-form" deps="angular-animate.js" animations="true" fixBase="true" module="formExample">
      <file name="index.html">
       <script>
         angular.module('formExample', [])

             $scope.userType = 'guest';
           }]);
       </script>
       <style>
        .my-form {
          transition:all linear 0.5s;
          background: transparent;
        }
        .my-form.ng-invalid {
          background: red;
        }
       </style>
       <form name="myForm" ng-controller="FormController" class="my-form">

   *
   * @description
   * Standard HTML text input with angular data binding, inherited by most of the `input` elements.
   *
   *
   * @param {string} ngModel Assignable angular expression to data-bind to.
   * @param {string=} name Property name of the form under which the control is published.
   * @param {string=} required Adds `required` validation error key if the value is not entered.
   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
   *    `required` when you want to data-bind to the `required` attribute.
   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
   *    minlength.
   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
   *    any length.
   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
   *    that contains the regular expression body that will be converted to a regular expression
   *    as in the ngPattern directive.
   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
   *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
   *    If the expression evaluates to a RegExp object, then this is used directly.
   *    If the expression evaluates to a string, then it will be converted to a RegExp
   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
   *    `new RegExp('^abc$')`.<br />
   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
   *    start at the index of the last search's match, thus not taking the whole input value into
   *    account.
   * @param {string=} ngChange Angular expression to be executed when input changes due to user
   *    interaction with the input element.
   * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.
   *    This parameter is ignored for input[type=password] controls, which will never trim the
   *    input.

     * Input with date validation and transformation. In browsers that do not yet support
     * the HTML5 date input, a text element will be used. In that case, text must be entered in a valid ISO-8601
     * date format (yyyy-MM-dd), for example: `2009-01-06`. Since many
     * modern browsers do not yet support this input type, it is important to provide cues to users on the
     * expected input format via a placeholder or label.
     *
     * The model must always be a Date object, otherwise Angular will throw an error.
     * Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string.
     *
     * The timezone to be used to read/write the `Date` instance in the model can be defined using

     * @param {string} ngModel Assignable angular expression to data-bind to.
     * @param {string=} name Property name of the form under which the control is published.
     * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`. This must be a
     *   valid ISO date string (yyyy-MM-dd). You can also use interpolation inside this attribute
     *   (e.g. `min="{{minDate | date:'yyyy-MM-dd'}}"`). Note that `min` will also add native HTML5
     *   constraint validation.
     * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`. This must be
     *   a valid ISO date string (yyyy-MM-dd). You can also use interpolation inside this attribute
     *   (e.g. `max="{{maxDate | date:'yyyy-MM-dd'}}"`). Note that `max` will also add native HTML5
     *   constraint validation.

     *   the `ngMin` expression evaluates to. Note that it does not set the `min` attribute.

     *   the `ngMax` expression evaluates to. Note that it does not set the `max` attribute.

   * @description
   * Input with month validation and transformation. In browsers that do not yet support
   * the HTML5 month input, a text element will be used. In that case, the text must be entered in a valid ISO-8601
   * month format (yyyy-MM), for example: `2009-01`.
   *
   * The model must always be a Date object, otherwise Angular will throw an error.
   * Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string.
   * If the model is not set to the first of the month, the next view to model update will set it
   * to the first of the month.
   *
   * The timezone to be used to read/write the `Date` instance in the model can be defined using
   * {@link ng.directive:ngModelOptions ngModelOptions}. By default, this is the timezone of the browser.
   *
   * @param {string} ngModel Assignable angular expression to data-bind to.
   * @param {string=} name Property name of the form under which the control is published.
   * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
   *   This must be a valid ISO month format (yyyy-MM). You can also use interpolation inside this
   *   attribute (e.g. `min="{{minMonth | date:'yyyy-MM'}}"`). Note that `min` will also add
   *   native HTML5 constraint validation.
   * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
   *   This must be a valid ISO month format (yyyy-MM). You can also use interpolation inside this
   *   attribute (e.g. `max="{{maxMonth | date:'yyyy-MM'}}"`). Note that `max` will also add
   *   native HTML5 constraint validation.
   * @param {(date|string)=} ngMin Sets the `min` validation constraint to the Date / ISO week string
   *   the `ngMin` expression evaluates to. Note that it does not set the `min` attribute.
   * @param {(date|string)=} ngMax Sets the `max` validation constraint to the Date / ISO week string
   *   the `ngMax` expression evaluates to. Note that it does not set the `max` attribute.

   * @param {string=} required Sets `required` validation error key if the value is not entered.
   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to

   * ## Issues with HTML5 constraint validation
   *
   * In browsers that follow the
   * [HTML5 specification](https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29),
   * `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
   * If a non-number is entered in the input, the browser will report the value as an empty string,
   * which means the view / model values in `ngModel` and subsequently the scope value
   * will also be an empty string.
   *
   *
   * @param {string} ngModel Assignable angular expression to data-bind to.
   * @param {string=} name Property name of the form under which the control is published.
   * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
   * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
   * @param {string=} required Sets `required` validation error key if the value is not entered.
   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
   *    `required` when you want to data-bind to the `required` attribute.
   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
   *    minlength.
   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
   *    any length.
   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
   *    that contains the regular expression body that will be converted to a regular expression
   *    as in the ngPattern directive.
   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
   *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
   *    If the expression evaluates to a RegExp object, then this is used directly.
   *    If the expression evaluates to a string, then it will be converted to a RegExp
   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
   *    `new RegExp('^abc$')`.<br />
   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to

   *    account.

  /**
   * @ngdoc input
   * @name input[range]
   *
   * @description
   * Native range input with validation and transformation.
   *
   * <div class="alert alert-warning">
   *   <p>
   *     In v1.5.9+, in order to avoid interfering with already existing, custom directives for
   *     `input[range]`, you need to let Angular know that you want to enable its built-in support.
   *     You can do this by adding the `ng-input-range` attribute to the input element. E.g.:
   *     `<input type="range" ng-input-range ... />`
   *   </p><br />
   *   <p>
   *     Input elements without the `ng-input-range` attibute will continue to be treated the same
   *     as in previous versions (e.g. their model value will be a string not a number and Angular
   *     will not take `min`/`max`/`step` attributes and properties into account).
   *   </p><br />
   *   <p>
   *     **Note:** From v1.6.x onwards, the support for `input[range]` will be always enabled and
   *     the `ng-input-range` attribute will have no effect.
   *   </p><br />
   *   <p>
   *     This documentation page refers to elements which have the built-in support enabled; i.e.
   *     elements _with_ the `ng-input-range` attribute.
   *   </p>
   * </div>
   *
   * The model for the range input must always be a `Number`.
   *
   * IE9 and other browsers that do not support the `range` type fall back
   * to a text input without any default values for `min`, `max` and `step`. Model binding,
   * validation and number parsing are nevertheless supported.
   *
   * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
   * in a way that never allows the input to hold an invalid value. That means:
   * - any non-numerical value is set to `(max + min) / 2`.
   * - any numerical value that is less than the current min val, or greater than the current max val
   * is set to the min / max val respectively.
   * - additionally, the current `step` is respected, so the nearest value that satisfies a step
   * is used.
   *
   * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
   * for more info.
   *
   * This has the following consequences for Angular:
   *
   * Since the element value should always reflect the current model value, a range input
   * will set the bound ngModel expression to the value that the browser has set for the
   * input element. For example, in the following input `<input type="range" ng-input-range ng-model="model.value">`,
   * if the application sets `model.value = null`, the browser will set the input to `'50'`.
   * Angular will then set the model to `50`, to prevent input and model value being out of sync.
   *
   * That means the model for range will immediately be set to `50` after `ngModel` has been
   * initialized. It also means a range input can never have the required error.
   *
   * This does not only affect changes to the model value, but also to the values of the `min`,
   * `max`, and `step` attributes. When these change in a way that will cause the browser to modify
   * the input value, Angular will also update the model value.
   *
   * Automatic value adjustment also means that a range input element can never have the `required`,
   * `min`, or `max` errors.
   *
   * However, `step` is currently only fully implemented by Firefox. Other browsers have problems
   * when the step value changes dynamically - they do not adjust the element value correctly, but
   * instead may set the `stepMismatch` error. If that's the case, the Angular will set the `step`
   * error on the input, and set the model to `undefined`.
   *
   * Note that `input[range]` is not compatible with `ngMax`, `ngMin`, and `ngStep`, because they do
   * not set the `min` and `max` attributes, which means that the browser won't automatically adjust
   * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.
   *
   * @param           ngInputRange The presense of this attribute enables the built-in support for
   *                  `input[range]`.
   * @param {string}  ngModel Assignable angular expression to data-bind to.
   * @param {string=} name Property name of the form under which the control is published.
   * @param {string=} min Sets the `min` validation to ensure that the value entered is greater
   *                  than `min`. Can be interpolated.
   * @param {string=} max Sets the `max` validation to ensure that the value entered is less than `max`.
   *                  Can be interpolated.
   * @param {string=} step Sets the `step` validation to ensure that the value entered matches the `step`
   *                  Can be interpolated.
   * @param {string=} ngChange Angular expression to be executed when the ngModel value changes due
   *                  to user interaction with the input element.
   * @param {expression=} ngChecked If the expression is truthy, then the `checked` attribute will be set on the
   *                      element. **Note** : `ngChecked` should not be used alongside `ngModel`.
   *                      Checkout {@link ng.directive:ngChecked ngChecked} for usage.

 * @description
 * HTML textarea element control with angular data-binding. The data-binding and validation
 * properties of this element are exactly the same as those of the
 * {@link ng.directive:input input element}.
 *
 * @param {string} ngModel Assignable angular expression to data-bind to.
 * @param {string=} name Property name of the form under which the control is published.
 * @param {string=} required Sets `required` validation error key if the value is not entered.
 * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
 *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
 *    `required` when you want to data-bind to the `required` attribute.
 * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
 *    minlength.
 * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
 *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of any
 *    length.
 * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
 *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
 *    If the expression evaluates to a RegExp object, then this is used directly.
 *    If the expression evaluates to a string, then it will be converted to a RegExp
 *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
 *    `new RegExp('^abc$')`.<br />
 *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
 *    start at the index of the last search's match, thus not taking the whole input value into
 *    account.
 * @param {string=} ngChange Angular expression to be executed when input changes due to user
 *    interaction with the input element.
 * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.
 *
 * @knownIssue
 *
 * When specifying the `placeholder` attribute of `<textarea>`, Internet Explorer will temporarily
 * insert the placeholder value as the textarea's content. If the placeholder value contains
 * interpolation (`{{ ... }}`), an error will be logged in the console when Angular tries to update
 * the value of the by-then-removed text node. This doesn't affect the functionality of the
 * textarea, but can be undesirable.
 *
 * You can work around this Internet Explorer issue by using `ng-attr-placeholder` instead of
 * `placeholder` on textareas, whenever you need interpolation in the placeholder value. You can
 * find more details on `ngAttr` in the
 * [Interpolation](guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes) section of the
 * Developer Guide.

 * the bound value.
 *
 * `ngValue` is useful when dynamically generating lists of radio buttons using

 *
 * Likewise, `ngValue` can be used to generate `<option>` elements for
 * the {@link select `select`} element. In that case however, only strings are supported
 * for the `value `attribute, so the resulting `ngModel` will always be a string.
 * Support for `select` models with non-string values is available via `ngOptions`.

 * @description
 * The `ngBind` attribute tells Angular to replace the text content of the specified HTML element

 * expression changes.
 *
 * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
 * `{{ expression }}` which is similar but less verbose.
 *
 * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
 * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
 * element attribute, it makes the bindings invisible to the user while the page is loading.
 *
 * An alternative solution to this problem would be using the
 * {@link ng.directive:ngCloak ngCloak} directive.
 *
 *

/**
 * @ngdoc directive
 * @name ngClass
 * @restrict AC
 *
 * @description
 * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
 * an expression that represents all classes to be added.
 *
 * The directive operates in three different ways, depending on which of three types the expression
 * evaluates to:
 *
 * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
 * names.
 *
 * 2. If the expression evaluates to an object, then for each key-value pair of the
 * object with a truthy value the corresponding key is used as a class name.
 *
 * 3. If the expression evaluates to an array, each element of the array should either be a string as in
 * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
 * to give you more control over what CSS classes appear. See the code below for an example of this.
 *
 *
 * The directive won't add duplicate classes if a particular class was already set.
 *
 * When the expression changes, the previously added classes are removed and only then are the
 * new classes added.
 *
 * @knownIssue
 * You should not use {@link guide/interpolation interpolation} in the value of the `class`
 * attribute, when using the `ngClass` directive on the same element.
 * See {@link guide/interpolation#known-issues here} for more info.
 *
 * @animations
 * | Animation                        | Occurs                              |
 * |----------------------------------|-------------------------------------|
 * | {@link ng.$animate#addClass addClass}       | just before the class is applied to the element   |
 * | {@link ng.$animate#removeClass removeClass} | just before the class is removed from the element |
 *
 * @element ANY
 * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
 *   of the evaluation can be a string representing space delimited class
 *   names, an array, or a map of class names to boolean values. In the case of a map, the
 *   names of the properties whose values are truthy will be added as css classes to the

      <input id="setbtn" type="button" value="set" ng-click="myVar='my-class'">
      <input id="clearbtn" type="button" value="clear" ng-click="myVar=''">
      <br>
      <span class="base-class" ng-class="myVar">Sample Text</span>
     </file>
     <file name="style.css">
       .base-class {
         transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
       }

       .base-class.my-class {
         color: red;
         font-size:3em;
       }
     </file>
     <file name="protractor.js" type="protractor">
       it('should check ng-class', function() {
         expect(element(by.css('.base-class')).getAttribute('class')).not.
           toMatch(/my-class/);

         element(by.id('setbtn')).click();

         expect(element(by.css('.base-class')).getAttribute('class')).
           toMatch(/my-class/);

         element(by.id('clearbtn')).click();

         expect(element(by.css('.base-class')).getAttribute('class')).not.
           toMatch(/my-class/);
       });
     </file>
   </example>


   ## ngClass and pre-existing CSS3 Transitions/Animations
   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
   to view the step by step details of {@link $animate#addClass $animate.addClass} and
   {@link $animate#removeClass $animate.removeClass}.

 * @description
 * The `ngCloak` directive is used to prevent the Angular html template from being briefly
 * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
 * directive to avoid the undesirable flicker effect caused by the html template display.
 *
 * The directive can be applied to the `<body>` element, but the preferred usage is to apply
 * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
 * of the browser view.
 *
 * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
 * `angular.min.js`.
 * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
 *
 * ```css
 * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
 *   display: none !important;
 * }
 * ```
 *
 * When this css rule is loaded by the browser, all html elements (including their children) that
 * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
 * during the compilation of the template it deletes the `ngCloak` element attribute, making
 * the compiled element visible.
 *
 * For the best result, the `angular.js` script must be loaded in the head section of the html
 * document; alternatively, the css rule above must be included in the external stylesheet of the
 * application.

/**
 * @ngdoc directive
 * @name ngController
 *
 * @description
 * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
 * supports the principles behind the Model-View-Controller design pattern.
 *
 * MVC components in angular:
 *
 * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
 *   are accessed through bindings.
 * * View — The template (HTML with data bindings) that is rendered into the View.
 * * Controller — The `ngController` directive specifies a Controller class; the class contains business
 *   logic behind the application to decorate the scope with functions and values
 *
 * Note that you can also attach controllers to the DOM by declaring it in a route definition
 * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
 * again using `ng-controller` in the template itself.  This will cause the controller to be attached
 * and executed twice.
 *
 * @element ANY
 * @scope
 * @priority 500
 * @param {expression} ngController Name of a constructor function registered with the current
 * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
 * that on the current scope evaluates to a constructor function.
 *
 * The controller instance can be published into a scope property by specifying
 * `ng-controller="as propertyName"`.
 *
 * If the current `$controllerProvider` is configured to use globals (via
 * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
 * also be the name of a globally accessible constructor function (not recommended).
 *
 * @example
 * Here is a simple form for editing user contact information. Adding, removing, clearing, and
 * greeting are methods declared on the controller (see source tab). These methods can
 * easily be called from the angular markup. Any changes to the data are automatically reflected
 * in the View without the need for a manual update.
 *
 * Two different declaration styles are included below:
 *
 * * one binds methods and properties directly onto the controller using `this`:
 * `ng-controller="SettingsController1 as settings"`
 * * one injects `$scope` into the controller:
 * `ng-controller="SettingsController2"`
 *
 * The second option is more common in the Angular community, and is generally used in boilerplates
 * and in this guide. However, there are advantages to binding properties directly to the controller
 * and avoiding scope.
 *
 * * Using `controller as` makes it obvious which controller you are accessing in the template when
 * multiple controllers apply to an element.
 * * If you are writing your controllers as classes you have easier access to the properties and
 * methods, which will appear on the scope, from inside the controller code.
 * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
 * inheritance masking primitives.
 *
 * This example demonstrates the `controller as` syntax.
 *
 * <example name="ngControllerAs" module="controllerAsExample">
 *   <file name="index.html">
 *    <div id="ctrl-as-exmpl" ng-controller="SettingsController1 as settings">

 * @description
 *
 * Angular has some features that can conflict with certain restrictions that are applied when using
 * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.
 *
 * If you intend to implement CSP with these rules then you must tell Angular not to use these
 * features.
 *
 * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
 *
 *
 * The following default rules in CSP affect Angular:
 *
 * * The use of `eval()`, `Function(string)` and similar functions to dynamically create and execute
 * code from strings is forbidden. Angular makes use of this in the {@link $parse} service to
 * provide a 30% increase in the speed of evaluating Angular expressions. (This CSP rule can be
 * disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would
 * weaken the protections offered by CSP.)
 *
 * * The use of inline resources, such as inline `<script>` and `<style>` elements, are forbidden.
 * This prevents apps from injecting custom styles directly into the document. Angular makes use of
 * this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}). To make these
 * directives work when a CSP rule is blocking inline styles, you must link to the `angular-csp.css`
 * in your HTML manually. (This CSP rule can be disabled with the CSP keyword `unsafe-inline`, but
 * it is generally not recommended as it would weaken the protections offered by CSP.)
 *
 * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking dynamic code
 * creation from strings (e.g., `unsafe-eval` not specified in CSP header) and automatically
 * deactivates this feature in the {@link $parse} service. This autodetection, however, triggers a
 * CSP error to be logged in the console:
 *
 * ```
 * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
 * script in the following Content Security Policy directive: "default-src 'self'". Note that
 * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
 * ```
 *
 * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
 * directive on an element of the HTML document that appears before the `<script>` tag that loads
 * the `angular.js` file.
 *
 * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
 *
 * You can specify which of the CSP related Angular features should be deactivated by providing
 * a value for the `ng-csp` attribute. The options are as follows:
 *
 * * no-inline-style: this stops Angular from injecting CSS styles into the DOM
 *
 * * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings
 *
 * You can use these values in the following combinations:
 *
 *
 * * No declaration means that Angular will assume that you can do inline styles, but it will do
 * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous
 * versions of Angular.
 *
 * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline
 * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous
 * versions of Angular.
 *
 * * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can
 * inject inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
 *
 * * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can
 * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
 *
 * * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject
 * styles nor use eval, which is the same as an empty: ng-csp.
 * E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
 *
 * @example
 * This example shows how to apply the `ngCsp` directive to the `html` tag.
   ```html
     <!doctype html>
     <html ng-app ng-csp>
     ...
     ...
     </html>

/**
 * @ngdoc directive
 * @name ngIf
 * @restrict A
 * @multiElement
 *
 * @description
 * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
 * {expression}. If the expression assigned to `ngIf` evaluates to a false
 * value then the element is removed from the DOM, otherwise a clone of the
 * element is reinserted into the DOM.
 *
 * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
 * element in the DOM rather than changing its visibility via the `display` css property.  A common
 * case when this difference is significant is when using css selectors that rely on an element's
 * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
 *
 * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
 * is created when the element is restored.  The scope created within `ngIf` inherits from
 * its parent scope using
 * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
 * An important implication of this is if `ngModel` is used within `ngIf` to bind to
 * a javascript primitive defined in the parent scope. In this case any modifications made to the
 * variable within the child scope will override (hide) the value in the parent scope.
 *
 * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
 * is if an element's class attribute is directly modified after it's compiled, using something like
 * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
 * the added class will be lost because the original compiled state is used to regenerate the element.
 *
 * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
 * and `leave` effects.
 *
 * @animations
 * | Animation                        | Occurs                               |
 * |----------------------------------|-------------------------------------|
 * | {@link ng.$animate#enter enter}  | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |
 * | {@link ng.$animate#leave leave}  | just before the `ngIf` contents are removed from the DOM |
 *
 * @element ANY
 * @scope
 * @priority 600
 * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
 *     the element is removed from the DOM tree. If it is truthy a copy of the compiled
 *     element is added to the DOM tree.
 *
 * @example

/**
 * @ngdoc directive
 * @name ngList

 * @description
 * Text input that converts between a delimited string and an array of strings. The default
 * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
 * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
 *
 * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
 * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
 *   list item is respected. This implies that the user of the directive is responsible for
 *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
 *   tab or newline character.
 * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
 *   when joining the list items back together) and whitespace around each list item is stripped
 *   before it is added to the model.

 * is set.
 * @property {*} $modelValue The value in the model that the control is bound to.
 * @property {Array.<Function>} $parsers Array of functions to execute, as a pipeline, whenever
       the control reads value from the DOM. The functions are called in array order, each passing

       {@link ngModel.NgModelController#$validators `$validators`} collection.

Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
`$viewValue`}.

Returning `undefined` from a parser means a parse error occurred. In that case,
no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
is set to `true`. The parse error is stored in `ngModel.$error.parse`.

 *
 * @property {Array.<Function>} $formatters Array of functions to execute, as a pipeline, whenever
       the model value changes. The functions are called in reverse array order, each passing the value through to the
       next. The last return value is used as the actual DOM value.
       Used to format / convert values for display in the control.
 * ```js

 *     return value.toUpperCase();
 *   }
 * }
 * ngModel.$formatters.push(formatter);
 * ```
 *
 * @property {Object.<string, function>} $validators A collection of validators that are applied
 *      whenever the model value changes. The key value within the object refers to the name of the
 *      validator while the function refers to the validation operation. The validation operation is
 *      provided with the model value as an argument and must return a true or false value depending
 *      on the response of that validation.
 *
 * ```js
 * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
 *   var value = modelValue || viewValue;
 *   return /[0-9]+/.test(value) &&
 *          /[a-z]+/.test(value) &&

 * };
 * ```
 *
 * @property {Object.<string, function>} $asyncValidators A collection of validations that are expected to
 *      perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
 *      is expected to return a promise when it is run during the model validation process. Once the promise
 *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
 *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
 *      value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
 *      is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
 *      will only run once all synchronous validators have passed.
 *
 * Please note that if $http is used then it is important that the server returns a success HTTP response code
 * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
 *
 * ```js
 * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
 *   var value = modelValue || viewValue;
 *
 *   // Lookup user by username
 *   return $http.get('/api/users/' + value).

 * };
 * ```
 *
 * @property {Array.<Function>} $viewChangeListeners Array of functions to execute whenever the
 *     view value has changed. It is called with no arguments, and its return value is ignored.
 *     This can be used in place of additional $watches against the model value.
 *
 * @property {Object} $error An object hash with all failing validator ids as keys.
 * @property {Object} $pending An object hash with all pending validator ids as keys.
 *
 * @property {boolean} $untouched True if control has not lost focus yet.

 * @description
 *
 * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
 * The controller contains services for data-binding, validation, CSS updates, and value formatting
 * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
 * listening to DOM events.
 * Such DOM related logic should be provided by other directives which make use of
 * `NgModelController` for data-binding to control elements.
 * Angular provides this DOM logic for most {@link input `input`} elements.
 * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
 * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
 *
 * @example
 * ### Custom Control Example
 * This example shows how to use `NgModelController` with a custom control to achieve
 * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
 * collaborate together to achieve the desired result.
 *
 * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
 * contents be edited in place by the user.
 *
 * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
 * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
 * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
 * that content using the `$sce` service.
 *
 * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
    <file name="style.css">
      [contenteditable] {
        border: 1px solid black;
        background-color: white;
        min-height: 20px;
      }

   * @description
   * Update the view value.
   *
   * This method should be called when a control wants to change the view value; typically,
   * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
   * directive calls it when the value of the input changes and {@link ng.directive:select select}
   * calls it when an option is selected.
   *
   * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
   * value sent directly for processing, finally to be applied to `$modelValue` and then the
   * **expression** specified in the `ng-model` attribute. Lastly, all the registered change listeners,
   * in the `$viewChangeListeners` list, are called.
   *
   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
   * and the `default` trigger is not listed, all those actions will remain pending until one of the
   * `updateOn` events is triggered on the DOM element.
   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
   * directive is used with a custom debounce for this particular event.
   * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
   * is specified, once the timer runs out.
   *
   * When used with standard inputs, the view value will always be a string (which is in some cases
   * parsed into another type, such as a `Date` object for `input[date]`.)
   * However, custom controls might also pass objects to this method. In this case, we should make
   * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
   * perform a deep watch of objects, it only looks for a change of identity. If you only change
   * the property of the object then ngModel will not realize that the object has changed and
   * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
   * not change properties of the copy once it has been passed to `$setViewValue`.
   * Otherwise you may cause the model value on the scope to change incorrectly.
   *
   * <div class="alert alert-info">
   * In any case, the value passed to the method should always reflect the current value
   * of the control. For example, if you are calling `$setViewValue` for an input element,
   * you should pass the input DOM value. Otherwise, the control and the scope model become
   * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
   * the control's DOM value in any way. If we want to change the control's DOM value
   * programmatically, we should update the `ngModel` scope expression. Its new value will be
   * picked up by the model controller, which will run it through the `$formatters`, `$render` it
   * to update the DOM, and finally call `$validate` on it.

/**
 * @ngdoc directive
 * @name ngModel
 *
 * @element input
 * @priority 1
 *
 * @description
 * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
 * property on the scope using {@link ngModel.NgModelController NgModelController},
 * which is created and exposed by this directive.
 *
 * `ngModel` is responsible for:
 *
 * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
 *   require.
 * - Providing validation behavior (i.e. required, number, email, url).
 * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
 * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
 *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
 * - Registering the control with its parent {@link ng.directive:form form}.
 *
 * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
 * current scope. If the property doesn't already exist on this scope, it will be created
 * implicitly and added to the scope.
 *
 * For best practices on using `ngModel`, see:
 *
 *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
 *
 * For basic examples, how to use `ngModel`, see:
 *
 *  - {@link ng.directive:input input}
 *    - {@link input[text] text}
 *    - {@link input[checkbox] checkbox}
 *    - {@link input[radio] radio}
 *    - {@link input[number] number}
 *    - {@link input[email] email}
 *    - {@link input[url] url}
 *    - {@link input[date] date}
 *    - {@link input[datetime-local] datetime-local}
 *    - {@link input[time] time}
 *    - {@link input[month] month}
 *    - {@link input[week] week}
 *  - {@link ng.directive:select select}
 *  - {@link ng.directive:textarea textarea}
 *
 * # Complex Models (objects or collections)
 *
 * By default, `ngModel` watches the model by reference, not value. This is important to know when
 * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
 * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
 *
 * The model must be assigned an entirely new object or collection before a re-rendering will occur.
 *
 * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
 * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
 * if the select is given the `multiple` attribute.
 *
 * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
 * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
 * not trigger a re-rendering of the model.
 *
 * # CSS classes
 * The following CSS classes are added and removed on the associated input/select/textarea element
 * depending on the validity of the model.
 *
 *  - `ng-valid`: the model is valid
 *  - `ng-invalid`: the model is invalid
 *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
 *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
 *  - `ng-pristine`: the control hasn't been interacted with yet
 *  - `ng-dirty`: the control has been interacted with
 *  - `ng-touched`: the control has been blurred
 *  - `ng-untouched`: the control hasn't been blurred
 *  - `ng-pending`: any `$asyncValidators` are unfulfilled
 *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
 *     by the {@link ngModel.NgModelController#$isEmpty} method
 *  - `ng-not-empty`: the view contains a non-empty value
 *
 * Keep in mind that ngAnimate can detect each of these classes when added and removed.
 *
 * ## Animation Hooks
 *
 * Animations within models are triggered when any of the associated CSS classes are added and removed
 * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
 * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
 * The animations that are triggered within ngModel are similar to how they work in ngClass and
 * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
 *
 * The following example shows a simple way to utilize CSS transitions to style an input element
 * that has been rendered as invalid after it has been validated:
 *
 * <pre>
 * //be sure to include ngAnimate as a module to hook into more
 * //advanced animations
 * .my-input {
 *   transition:0.5s linear all;
 *   background: white;
 * }
 * .my-input.ng-invalid {
 *   background: red;
 *   color:white;
 * }
 * </pre>
 *
 * @example
 * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample" name="ng-model">
     <file name="index.html">
       <script>
        angular.module('inputExample', [])
          .controller('ExampleController', ['$scope', function($scope) {
            $scope.val = '1';
          }]);
       </script>
       <style>
         .my-input {
           transition:all linear 0.5s;
           background: transparent;
         }
         .my-input.ng-invalid {
           color:white;
           background: red;
         }
       </style>
       <p id="inputDescription">
        Update input to see transitions when valid/invalid.
        Integer is a valid value.
       </p>
       <form name="testForm" ng-controller="ExampleController">
         <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input"
                aria-describedby="inputDescription" />
       </form>
     </file>
 * </example>
 *
 * ## Binding to a getter/setter
 *
 * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
 * function that returns a representation of the model when called with zero arguments, and sets
 * the internal state of a model when called with an argument. It's sometimes useful to use this
 * for models that have an internal representation that's different from what the model exposes
 * to the view.
 *
 * <div class="alert alert-success">
 * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
 * frequently than other parts of your code.
 * </div>
 *
 * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
 * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
 * a `<form>`, which will enable this behavior for all `<input>`s within it. See
 * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
 *
 * The following example shows how to use `ngModel` with a getter/setter:

/**
 * @ngdoc directive
 * @name ngModelOptions
 *
 * @description
 * Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of
 * events that will trigger a model update and/or a debouncing delay so that the actual update only
 * takes place when a timer expires; this timer will be reset after another change takes place.
 *
 * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
 * be different from the value in the actual model. This means that if you update the model you
 * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in
 * order to make sure it is synchronized with the model and that any debounced action is canceled.
 *
 * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`}
 * method is by making sure the input is placed inside a form that has a `name` attribute. This is
 * important because `form` controllers are published to the related scope under the name in their
 * `name` attribute.
 *
 * Any pending changes will take place immediately when an enclosing form is submitted via the
 * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
 * to have access to the updated model.
 *
 * `ngModelOptions` has an effect on the element it's declared on and its descendants.
 *
 * @param {Object} ngModelOptions options to apply to the current model. Valid keys are:
 *   - `updateOn`: string specifying which event should the input be bound to. You can set several
 *     events using an space delimited list. There is a special event called `default` that
 *     matches the default events belonging of the control.
 *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
 *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
 *     custom value for each event. For example:
 *     `ng-model-options="{ updateOn: 'default blur', debounce: { 'default': 500, 'blur': 0 } }"`
 *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
 *     not validate correctly instead of the default behavior of setting the model to undefined.
 *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
       `ngModel` as getters/setters.
 *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
 *     `<input type="date">`, `<input type="time">`, ... . It understands UTC/GMT and the
 *     continental US time zone abbreviations, but for general use, use a time zone offset, for
 *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
 *     If not specified, the timezone of the browser will be used.
 *
 * @example

  The following example shows how to override immediate updates. Changes on the inputs within the
  form will update the model only when the control loses focus (blur event). If `escape` key is
  pressed while the input field is focused, the value is reset to the value in the current model.

  <example name="ngModelOptions-directive-blur" module="optionsExample">
    <file name="index.html">
      <div ng-controller="ExampleController">
        <form name="userForm">

                   ng-model-options="{ updateOn: 'blur' }"
                   ng-keyup="cancel($event)" />
          </label><br />
          <label>Other data:
            <input type="text" ng-model="user.data" />
          </label><br />
        </form>
        <pre>user.name = <span ng-bind="user.name"></span></pre>

  This one shows how to debounce model changes. Model will be updated only 1 sec after last change.
  If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty.

/**
 * @ngdoc directive
 * @name ngOptions
 * @restrict A
 *
 * @description
 *
 * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
 * elements for the `<select>` element using the array or object obtained by evaluating the
 * `ngOptions` comprehension expression.
 *
 * In many cases, {@link ng.directive:ngRepeat ngRepeat} can be used on `<option>` elements
 * instead of `ngOptions` to achieve a similar result.
 * However, `ngOptions` provides some benefits such as reducing memory and
 * increasing speed by not creating a new scope for each repeated instance, as well as providing
 * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
 * comprehension expression. `ngOptions` should be used when the `<select>` model needs to be bound
 *  to a non-string value. This is because an option element can only be bound to string values at
 * present.
 *
 * When an item in the `<select>` menu is selected, the array element or object property
 * represented by the selected option will be bound to the model identified by the `ngModel`
 * directive.
 *
 * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
 * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
 * option. See example below for demonstration.
 *
 * ## Complex Models (objects or collections)
 *
 * By default, `ngModel` watches the model by reference, not value. This is important to know when
 * binding the select to a model that is an object or a collection.
 *
 * One issue occurs if you want to preselect an option. For example, if you set
 * the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection,
 * because the objects are not identical. So by default, you should always reference the item in your collection
 * for preselections, e.g.: `$scope.selected = $scope.collection[3]`.
 *
 * Another solution is to use a `track by` clause, because then `ngOptions` will track the identity
 * of the item not by reference, but by the result of the `track by` expression. For example, if your
 * collection items have an id property, you would `track by item.id`.
 *
 * A different issue with objects or collections is that ngModel won't detect if an object property or
 * a collection item changes. For that reason, `ngOptions` additionally watches the model using
 * `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute.
 * This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection
 * has not changed identity, but only a property on the object or an item in the collection changes.
 *
 * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection
 * if the model is an array). This means that changing a property deeper than the first level inside the
 * object/collection will not trigger a re-rendering.
 *
 * ## `select` **`as`**
 *
 * Using `select` **`as`** will bind the result of the `select` expression to the model, but
 * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
 * or property name (for object data sources) of the value within the collection. If a **`track by`** expression
 * is used, the result of that expression will be set as the value of the `option` and `select` elements.
 *
 *
 * ### `select` **`as`** and **`track by`**
 *
 * <div class="alert alert-warning">
 * Be careful when using `select` **`as`** and **`track by`** in the same expression.
 * </div>
 *
 * Given this array of items on the $scope:
 *
 * ```js
 * $scope.items = [{
 *   id: 1,
 *   label: 'aLabel',
 *   subItem: { name: 'aSubItem' }
 * }, {
 *   id: 2,
 *   label: 'bLabel',
 *   subItem: { name: 'bSubItem' }
 * }];
 * ```
 *
 * This will work:
 *
 * ```html
 * <select ng-options="item as item.label for item in items track by item.id" ng-model="selected"></select>
 * ```
 * ```js
 * $scope.selected = $scope.items[0];
 * ```
 *
 * but this will not work:
 *
 * ```html
 * <select ng-options="item.subItem as item.label for item in items track by item.id" ng-model="selected"></select>
 * ```
 * ```js
 * $scope.selected = $scope.items[0].subItem;
 * ```
 *
 * In both examples, the **`track by`** expression is applied successfully to each `item` in the
 * `items` array. Because the selected option has been set programmatically in the controller, the
 * **`track by`** expression is also applied to the `ngModel` value. In the first example, the
 * `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with
 * no issue. In the second example, the `ngModel` value is `items[0].subItem` and the **`track by`**
 * expression evaluates to `items[0].subItem.id` (which is undefined). As a result, the model value
 * is not matched against any `<option>` and the `<select>` appears as having no selected value.
 *
 *
 * @param {string} ngModel Assignable angular expression to data-bind to.
 * @param {string=} name Property name of the form under which the control is published.
 * @param {string=} required The control is considered valid only if value is entered.
 * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
 *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
 *    `required` when you want to data-bind to the `required` attribute.
 * @param {comprehension_expression=} ngOptions in one of the following forms:
 *
 *   * for array data sources:
 *     * `label` **`for`** `value` **`in`** `array`
 *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
 *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
 *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array`

 *      of `object` during iteration.
 *   * `key`: local variable which will refer to a property name in `object` during iteration.
 *   * `label`: The result of this expression will be the label for `<option>` element. The
 *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
 *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
 *      element. If not specified, `select` expression will default to `value`.
 *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
 *      DOM element.
 *   * `disable`: The result of this expression will be used to disable the rendered `<option>`
 *      element. Return `true` to disable.
 *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
 *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
 *     `value` variable (e.g. `value.propertyName`). With this the selection is preserved
 *      even when the options are recreated (e.g. reloaded from the server).

/**
 * @ngdoc directive
 * @name ngPluralize
 * @restrict EA
 *
 * @description
 * `ngPluralize` is a directive that displays messages according to en-US localization rules.
 * These rules are bundled with angular.js, but can be overridden
 * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
 * by specifying the mappings between
 * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
 * and the strings to be displayed.
 *
 * # Plural categories and explicit number rules
 * There are two
 * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
 * in Angular's default en-US locale: "one" and "other".
 *
 * While a plural category may match many numbers (for example, in en-US locale, "other" can match
 * any number that is not 1), an explicit number rule can only match one number. For example, the
 * explicit number rule for "3" matches the number 3. There are examples of plural categories
 * and explicit number rules throughout the rest of this documentation.
 *
 * # Configuring ngPluralize
 * You configure ngPluralize by providing 2 attributes: `count` and `when`.
 * You can also provide an optional attribute, `offset`.
 *
 * The value of the `count` attribute can be either a string or an {@link guide/expression
 * Angular expression}; these are evaluated on the current scope for its bound value.
 *
 * The `when` attribute specifies the mappings between plural categories and the actual
 * string to be displayed. The value of the attribute should be a JSON object.
 *
 * The following example shows how to configure ngPluralize:
 *
 * ```html
 * <ng-pluralize count="personCount"
                 when="{'0': 'Nobody is viewing.',
 *                      'one': '1 person is viewing.',
 *                      'other': '{} people are viewing.'}">
 * </ng-pluralize>
 *```
 *
 * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
 * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
 * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
 * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
 * show "a dozen people are viewing".
 *
 * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
 * into pluralized strings. In the previous example, Angular will replace `{}` with
 * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
 * for <span ng-non-bindable>{{numberExpression}}</span>.
 *
 * If no rule is defined for a category, then an empty string is displayed and a warning is generated.
 * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
 *
 * # Configuring ngPluralize with offset
 * The `offset` attribute allows further customization of pluralized text, which can result in
 * a better user experience. For example, instead of the message "4 people are viewing this document",
 * you might display "John, Kate and 2 others are viewing this document".
 * The offset attribute allows you to offset a number by any desired value.
 * Let's take a look at an example:
 *
 * ```html
 * <ng-pluralize count="personCount" offset=2
 *               when="{'0': 'Nobody is viewing.',
 *                      '1': '{{person1}} is viewing.',
 *                      '2': '{{person1}} and {{person2}} are viewing.',
 *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
 *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
 * </ng-pluralize>
 * ```
 *
 * Notice that we are still using two plural categories(one, other), but we added
 * three explicit number rules 0, 1 and 2.
 * When one person, perhaps John, views the document, "John is viewing" will be shown.
 * When three people view the document, no explicit number rule is found, so
 * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
 * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
 * is shown.
 *
 * Note that when you specify offsets, you must provide explicit number rules for
 * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
 * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
 * plural categories "one" and "other".
 *
 * @param {string|expression} count The variable to be bound to.
 * @param {string} when The mapping between plural category to its corresponding strings.
 * @param {number=} offset Offset to deduct from the total number.
 *

 *
 * | Variable  | Type            | Details                                                                     |

 *
 *
 * # Iterating over object properties
 *
 * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
 * syntax:
 *
 * ```js
 * <div ng-repeat="(key, value) in myObj"> ... </div>
 * ```
 *
 * However, there are a few limitations compared to array iteration:
 *
 * - The JavaScript specification does not define the order of keys
 *   returned for an object, so Angular relies on the order returned by the browser
 *   when running `for key in myObj`. Browsers generally follow the strategy of providing
 *   keys in the order in which they were defined, although there are exceptions when keys are deleted
 *   and reinstated. See the
 *   [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
 *
 * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
 *   it's a prefix used by Angular for public (`$`) and private (`$$`) properties.
 *
 * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
 *   objects, and will throw an error if used with one.
 *
 * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
 * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
 * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
 * or implement a `$watch` on the object yourself.
 *
 *
 * # Tracking and Duplicates
 *
 * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
 * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM:
 *
 * * When an item is added, a new instance of the template is added to the DOM.
 * * When an item is removed, its template instance is removed from the DOM.
 * * When items are reordered, their respective templates are reordered in the DOM.
 *
 * To minimize creation of DOM elements, `ngRepeat` uses a function
 * to "keep track" of all items in the collection and their corresponding DOM elements.
 * For example, if an item is added to the collection, `ngRepeat` will know that all other items
 * already have DOM elements, and will not re-render them.
 *
 * The default tracking function (which tracks items by their identity) does not allow
 * duplicate items in arrays. This is because when there are duplicates, it is not possible
 * to maintain a one-to-one mapping between collection items and DOM elements.
 *
 * If you do need to repeat duplicate items, you can substitute the default tracking behavior
 * with your own using the `track by` expression.
 *
 * For example, you may track items by the index of each item in the collection, using the
 * special scope property `$index`:
 * ```html
 *    <div ng-repeat="n in [42, 42, 43, 43] track by $index">
 *      {{n}}
 *    </div>
 * ```
 *
 * You may also use arbitrary expressions in `track by`, including references to custom functions
 * on the scope:
 * ```html
 *    <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
 *      {{n}}
 *    </div>
 * ```
 *
 * <div class="alert alert-success">
 * If you are working with objects that have a unique identifier property, you should track
 * by this identifier instead of the object instance. Should you reload your data later, `ngRepeat`
 * will not have to rebuild the DOM elements for items it has already rendered, even if the
 * JavaScript objects in the collection have been substituted for new ones. For large collections,
 * this significantly improves rendering performance. If you don't have a unique identifier,
 * `track by $index` can also provide a performance boost.
 * </div>
 *
 * ```html
 *    <div ng-repeat="model in collection track by model.id">
 *      {{model.name}}
 *    </div>
 * ```
 *
 * <br />
 * <div class="alert alert-warning">
 * Avoid using `track by $index` when the repeated template contains
 * {@link guide/expression#one-time-binding one-time bindings}. In such cases, the `nth` DOM
 * element will always be matched with the `nth` item of the array, so the bindings on that element
 * will not be updated even when the corresponding item changes, essentially causing the view to get
 * out-of-sync with the underlying data.
 * </div>
 *
 * When no `track by` expression is provided, it is equivalent to tracking by the built-in
 * `$id` function, which tracks items by their identity:
 * ```html
 *    <div ng-repeat="obj in collection track by $id(obj)">
 *      {{obj.prop}}
 *    </div>
 * ```
 *
 * <br />
 * <div class="alert alert-warning">
 * **Note:** `track by` must always be the last expression:
 * </div>
 * ```
 *    <div ng-repeat="model in collection | orderBy: 'id' as filtered_result track by model.id">
 *      {{model.name}}
 *    </div>
 * ```
 *
 *
 * # Special repeat start and end points
 * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
 * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
 * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
 * up to and including the ending HTML tag where **ng-repeat-end** is placed.
 *
 * The example below makes use of this feature:
 * ```html
 *   <header ng-repeat-start="item in items">
 *     Header {{ item }}
 *   </header>
 *   <div class="body">
 *     Body {{ item }}
 *   </div>
 *   <footer ng-repeat-end>
 *     Footer {{ item }}
 *   </footer>
 * ```
 *
 * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
 * ```html
 *   <header>
 *     Header A
 *   </header>
 *   <div class="body">
 *     Body A
 *   </div>
 *   <footer>
 *     Footer A
 *   </footer>
 *   <header>
 *     Header B
 *   </header>
 *   <div class="body">
 *     Body B
 *   </div>
 *   <footer>
 *     Footer B
 *   </footer>
 * ```
 *
 * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
 * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).

 * @animations
 * | Animation                        | Occurs                              |
 * |----------------------------------|-------------------------------------|
 * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter |
 * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out |
 * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered |
 *
 * See the example below for defining CSS animations with ngRepeat.
 *
 * @element ANY
 * @scope
 * @priority 1000
 * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
 *   formats are currently supported:
 *
 *   * `variable in expression` – where variable is the user defined loop variable and `expression`
 *     is a scope expression giving the collection to enumerate.
 *
 *     For example: `album in artist.albums`.
 *
 *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
 *     and `expression` is the scope expression giving the collection to enumerate.
 *
 *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
 *
 *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
 *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
 *     is specified, ng-repeat associates elements by identity. It is an error to have
 *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
 *     mapped to the same DOM element, which is not possible.)
 *
 *     Note that the tracking expression must come last, after any filters, and the alias expression.
 *
 *     For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements
 *     will be associated by item identity in the array.
 *
 *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
 *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
 *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM
 *     element in the same way in the DOM.
 *
 *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
 *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`
 *     property is same.
 *
 *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
 *     to items in conjunction with a tracking expression.
 *
 *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
 *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
 *     when a filter is active on the repeater, but the filtered result set is empty.
 *
 *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
 *     the items have been processed through the filter.
 *
 *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end
 *     (and not as operator, inside an expression).
 *
 *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` .
 *
 * @example
 * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
 * results by name or by age. New (entering) and removed (leaving) items are animated.

/**
 * @ngdoc directive
 * @name ngShow
 * @multiElement
 *
 * @description
 * The `ngShow` directive shows or hides the given HTML element based on the expression provided to
 * the `ngShow` attribute.
 *
 * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
 * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
 * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
 * {@link ng.directive:ngCsp ngCsp}).
 *
 * ```html
 * <!-- when $scope.myValue is truthy (element is visible) -->
 * <div ng-show="myValue"></div>
 *
 * <!-- when $scope.myValue is falsy (element is hidden) -->
 * <div ng-show="myValue" class="ng-hide"></div>
 * ```
 *
 * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added
 * to the class attribute on the element causing it to become hidden. When truthy, the `.ng-hide`
 * CSS class is removed from the element causing the element not to appear hidden.
 *
 * ## Why is `!important` used?
 *
 * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
 * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
 * simple as changing the display style on a HTML list item would make hidden elements appear
 * visible. This also becomes a bigger issue when dealing with CSS frameworks.
 *
 * By using `!important`, the show and hide behavior will work as expected despite any clash between
 * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
 * developer chooses to override the styling to change how to hide an element then it is just a
 * matter of using `!important` in their own CSS code.
 *
 * ### Overriding `.ng-hide`
 *
 * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
 * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
 * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
 * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
 *
 * ```css
 * .ng-hide:not(.ng-hide-animate) {
 *   /&#42; These are just alternative ways of hiding an element &#42;/
 *   display: block!important;
 *   position: absolute;
 *   top: -9999px;
 *   left: -9999px;
 * }
 * ```
 *
 * By default you don't need to override anything in CSS and the animations will work around the
 * display style.
 *
 * ## A note about animations with `ngShow`
 *
 * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
 * directive expression is true and false. This system works like the animation system present with
 * `ngClass` except that you must also include the `!important` flag to override the display
 * property so that the elements are not actually hidden during the animation.
 *
 * ```css
 * /&#42; A working example can be found at the bottom of this page. &#42;/
 * .my-element.ng-hide-add, .my-element.ng-hide-remove {
 *   transition: all 0.5s linear;
 * }
 *
 * .my-element.ng-hide-add { ... }
 * .my-element.ng-hide-add.ng-hide-add-active { ... }
 * .my-element.ng-hide-remove { ... }
 * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
 * ```
 *
 * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
 * to block during animation states - ngAnimate will automatically handle the style toggling for you.

/**
 * @ngdoc directive
 * @name ngHide
 * @multiElement
 *
 * @description
 * The `ngHide` directive shows or hides the given HTML element based on the expression provided to
 * the `ngHide` attribute.
 *
 * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
 * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
 * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
 * {@link ng.directive:ngCsp ngCsp}).
 *
 * ```html
 * <!-- when $scope.myValue is truthy (element is hidden) -->
 * <div ng-hide="myValue" class="ng-hide"></div>
 *
 * <!-- when $scope.myValue is falsy (element is visible) -->
 * <div ng-hide="myValue"></div>
 * ```
 *
 * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added
 * to the class attribute on the element causing it to become hidden. When falsy, the `.ng-hide`
 * CSS class is removed from the element causing the element not to appear hidden.
 *
 * ## Why is `!important` used?
 *
 * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
 * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
 * simple as changing the display style on a HTML list item would make hidden elements appear
 * visible. This also becomes a bigger issue when dealing with CSS frameworks.

 * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a

/**

 *
 * @description
 * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
 * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
 * as specified in the template.
 *
 * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
 * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
 * matches the value obtained from the evaluated expression. In other words, you define a container element
 * (where you place the directive), place an expression on the **`on="..."` attribute**
 * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
 * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
 * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
 * attribute is displayed.
 *
 * <div class="alert alert-info">
 * Be aware that the attribute values to match against cannot be expressions. They are interpreted
 * as literal string values to match against.
 * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
 * value of the expression `$scope.someVal`.
 * </div>

 * | {@link ng.$animate#enter enter}  | after the ngSwitch contents change and the matched child element is placed inside the container |
 * | {@link ng.$animate#leave leave}  | after the ngSwitch contents change and just before the former contents are removed from the DOM |
 *
 * @usage
 *
 * ```

 *   <ANY ng-switch-when="matchValue1">...</ANY>
 *   <ANY ng-switch-when="matchValue2">...</ANY>

 *
 *
 * @scope

 * @param {*} ngSwitch|on expression to match against <code>ng-switch-when</code>.
 * On child elements add:
 *
 * * `ngSwitchWhen`: the case statement to match against. If match then this
 *   case will be displayed. If the same match appears multiple times, all the
 *   elements will be displayed. It is possible to associate multiple values to
 *   the same `ngSwitchWhen` by defining the optional attribute
 *   `ngSwitchWhenSeparator`. The separator will be used to split the value of
 *   the `ngSwitchWhen` attribute into multiple tokens, and the element will show
 *   if any of the `ngSwitch` evaluates to any of these tokens.
 * * `ngSwitchDefault`: the default case when no other case match. If there
 *   are multiple default cases, all of them will be displayed when no other
 *   case match.

/**
 * @ngdoc directive
 * @name ngTransclude
 * @restrict EAC
 *
 * @description
 * Directive that marks the insertion point for the transcluded DOM of the nearest parent directive that uses transclusion.
 *
 * You can specify that you want to insert a named transclusion slot, instead of the default slot, by providing the slot name
 * as the value of the `ng-transclude` or `ng-transclude-slot` attribute.
 *
 * If the transcluded content is not empty (i.e. contains one or more DOM nodes, including whitespace text nodes), any existing
 * content of this element will be removed before the transcluded content is inserted.
 * If the transcluded content is empty, the existing content is left intact. This lets you provide fallback content in the case
 * that no transcluded content is provided.
 *
 * @element ANY
 *
 * @param {string} ngTransclude|ngTranscludeSlot the name of the slot to insert at this point. If this is not provided, is empty
 *                                               or its value is the same as the name of the attribute then the default slot is used.
 *
 * @example
 * ### Basic transclusion
 * This example demonstrates basic transclusion of content into a component directive.
 * <example name="simpleTranscludeExample" module="transcludeExample">
 *   <file name="index.html">
 *     <script>
 *       angular.module('transcludeExample', [])

/**
 * @ngdoc directive
 * @name select
 * @restrict E
 *
 * @description
 * HTML `SELECT` element with angular data-binding.
 *
 * The `select` directive is used together with {@link ngModel `ngModel`} to provide data-binding
 * between the scope and the `<select>` control (including setting default values).
 * It also handles dynamic `<option>` elements, which can be added using the {@link ngRepeat `ngRepeat}` or
 * {@link ngOptions `ngOptions`} directives.
 *
 * When an item in the `<select>` menu is selected, the value of the selected option will be bound
 * to the model identified by the `ngModel` directive. With static or repeated options, this is
 * the content of the `value` attribute or the textContent of the `<option>`, if the value attribute is missing.
 * For dynamic options, use interpolation inside the `value` attribute or the `textContent`. Using
 * {@link ngValue ngValue} is also possible (as it sets the `value` attribute), and will take
 * precedence over `value` and `textContent`.
 *
 * <div class="alert alert-warning">
 * Note that the value of a `select` directive used without `ngOptions` is always a string.
 * When the model needs to be bound to a non-string value, you must either explicitly convert it
 * using a directive (see example below) or use `ngOptions` to specify the set of options.
 * This is because an option element can only be bound to string values at present.
 * </div>
 *
 * If the viewValue of `ngModel` does not match any of the options, then the control
 * will automatically add an "unknown" option, which it then removes when the mismatch is resolved.
 *
 * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
 * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
 * option. See example below for demonstration.
 *
 * <div class="alert alert-info">
 * In many cases, `ngRepeat` can be used on `<option>` elements instead of {@link ng.directive:ngOptions
 * ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits, such as
 * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
 * comprehension expression, and additionally in reducing memory and increasing speed by not creating
 * a new scope for each repeated instance.
 * </div>
 *
 *
 * @param {string} ngModel Assignable angular expression to data-bind to.
 * @param {string=} name Property name of the form under which the control is published.
 * @param {string=} multiple Allows multiple options to be selected. The selected values will be
 *     bound to the model as an array.
 * @param {string=} required Sets `required` validation error key if the value is not entered.
 * @param {string=} ngRequired Adds required attribute and required validation constraint to
 * the element when the ngRequired expression evaluates to true. Use ngRequired instead of required
 * when you want to data-bind to the required attribute.
 * @param {string=} ngChange Angular expression to be executed when selected option(s) changes due to user
 *    interaction with the select element.
 * @param {string=} ngOptions sets the options that the select is populated with and defines what is
 * set on the model on selection. See {@link ngOptions `ngOptions`}.
 *
 * @example
 * ### Simple `select` elements with static options
 *
 * <example name="static-select" module="staticSelect">
 * <file name="index.html">
 * <div ng-controller="ExampleController">
 *   <form name="myForm">
 *     <label for="singleSelect"> Single select: </label><br>
 *     <select name="singleSelect" ng-model="data.singleSelect">
 *       <option value="option-1">Option 1</option>
 *       <option value="option-2">Option 2</option>
 *     </select><br>
 *
 *     <label for="singleSelect"> Single select with "not selected" option and dynamic option values: </label><br>
 *     <select name="singleSelect" id="singleSelect" ng-model="data.singleSelect">
 *       <option value="">---Please select---</option> <!-- not selected / blank option -->
 *       <option value="{{data.option1}}">Option 1</option> <!-- interpolation -->
 *       <option value="option-2">Option 2</option>
 *     </select><br>
 *     <button ng-click="forceUnknownOption()">Force unknown option</button><br>
 *     <tt>singleSelect = {{data.singleSelect}}</tt>
 *
 *     <hr>
 *     <label for="multipleSelect"> Multiple select: </label><br>
 *     <select name="multipleSelect" id="multipleSelect" ng-model="data.multipleSelect" multiple>
 *       <option value="option-1">Option 1</option>
 *       <option value="option-2">Option 2</option>
 *       <option value="option-3">Option 3</option>
 *     </select><br>
 *     <tt>multipleSelect = {{data.multipleSelect}}</tt><br/>
 *   </form>
 * </div>
 * </file>
 * <file name="app.js">
 *  angular.module('staticSelect', [])
 *    .controller('ExampleController', ['$scope', function($scope) {
 *      $scope.data = {
 *       singleSelect: null,
 *       multipleSelect: [],
 *       option1: 'option-1'
 *      };
 *
 *      $scope.forceUnknownOption = function() {
 *        $scope.data.singleSelect = 'nonsense';
 *      };
 *   }]);
 * </file>
 *</example>
 *
 * ### Using `ngRepeat` to generate `select` options
 * <example name="ngrepeat-select" module="ngrepeatSelect">
 * <file name="index.html">
 * <div ng-controller="ExampleController">
 *   <form name="myForm">
 *     <label for="repeatSelect"> Repeat select: </label>
 *     <select name="repeatSelect" id="repeatSelect" ng-model="data.repeatSelect">
 *       <option ng-repeat="option in data.availableOptions" value="{{option.id}}">{{option.name}}</option>
 *     </select>
 *   </form>
 *   <hr>
 *   <tt>repeatSelect = {{data.repeatSelect}}</tt><br/>
 * </div>
 * </file>
 * <file name="app.js">
 *  angular.module('ngrepeatSelect', [])
 *    .controller('ExampleController', ['$scope', function($scope) {
 *      $scope.data = {
 *       repeatSelect: null,
 *       availableOptions: [
 *         {id: '1', name: 'Option A'},
 *         {id: '2', name: 'Option B'},
 *         {id: '3', name: 'Option C'}
 *       ]
 *      };
 *   }]);
 * </file>
 *</example>
 *
 *
 * ### Using `select` with `ngOptions` and setting a default value
 * See the {@link ngOptions ngOptions documentation} for more `ngOptions` usage examples.
 *
 * <example name="select-with-default-values" module="defaultValueSelect">
 * <file name="index.html">
 * <div ng-controller="ExampleController">
 *   <form name="myForm">
 *     <label for="mySelect">Make a choice:</label>
 *     <select name="mySelect" id="mySelect"
 *       ng-options="option.name for option in data.availableOptions track by option.id"
 *       ng-model="data.selectedOption"></select>
 *   </form>
 *   <hr>
 *   <tt>option = {{data.selectedOption}}</tt><br/>
 * </div>
 * </file>
 * <file name="app.js">
 *  angular.module('defaultValueSelect', [])
 *    .controller('ExampleController', ['$scope', function($scope) {
 *      $scope.data = {
 *       availableOptions: [
 *         {id: '1', name: 'Option A'},
 *         {id: '2', name: 'Option B'},
 *         {id: '3', name: 'Option C'}
 *       ],
 *       selectedOption: {id: '3', name: 'Option C'} //This sets the default value of the select in the ui
 *       };
 *   }]);
 * </file>
 *</example>
 *
 *
 * ### Binding `select` to a non-string value via `ngModel` parsing / formatting
 *
 * <example name="select-with-non-string-options" module="nonStringSelect">
 *   <file name="index.html">
 *     <select ng-model="model.id" convert-to-number>
 *       <option value="0">Zero</option>
 *       <option value="1">One</option>
 *       <option value="2">Two</option>
 *     </select>
 *     {{ model }}
 *   </file>
 *   <file name="app.js">
 *     angular.module('nonStringSelect', [])
 *       .run(function($rootScope) {
 *         $rootScope.model = { id: 2 };
 *       })
 *       .directive('convertToNumber', function() {
 *         return {
 *           require: 'ngModel',
 *           link: function(scope, element, attrs, ngModel) {
 *             ngModel.$parsers.push(function(val) {
 *               return parseInt(val, 10);
 *             });
 *             ngModel.$formatters.push(function(val) {
 *               return '' + val;
 *             });
 *           }
 *         };
 *       });
 *   </file>
 *   <file name="protractor.js" type="protractor">

/**
 * @ngdoc directive
 * @name ngRequired
 * @restrict A
 *
 * @description
 *
 * ngRequired adds the required {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
 * It is most often used for {@link input `input`} and {@link select `select`} controls, but can also be
 * applied to custom controls.
 *
 * The directive sets the `required` attribute on the element if the Angular expression inside
 * `ngRequired` evaluates to true. A special directive for setting `required` is necessary because we
 * cannot use interpolation inside `required`. See the {@link guide/interpolation interpolation guide}
 * for more info.
 *
 * The validator will set the `required` error key to true if the `required` attribute is set and
 * calling {@link ngModel.NgModelController#$isEmpty `NgModelController.$isEmpty`} with the
 * {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`} returns `true`. For example, the
 * `$isEmpty()` implementation for `input[text]` checks the length of the `$viewValue`. When developing
 * custom controls, `$isEmpty()` can be overwritten to account for a $viewValue that is not string-based.
 *

 * ngPattern adds the pattern {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
 * It is most often used for text-based {@link input `input`} controls, but can also be applied to custom text-based controls.
 *
 * The validator sets the `pattern` error key if the {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`}
 * does not match a RegExp which is obtained by evaluating the Angular expression given in the

 * * If the expression evaluates to a RegExp object, then this is used directly.
 * * If the expression evaluates to a string, then it will be converted to a RegExp after wrapping it
 * in `^` and `$` characters. For instance, `"abc"` will be converted to `new RegExp('^abc$')`.
 *
 * <div class="alert alert-info">

 * `ngMinlength` attribute value.
 *
 * <div class="alert alert-info">
 * **Note:** This directive is also added when the plain `minlength` attribute is used, with two
 * differences:
 * <ol>
 *   <li>
 *     `ngMinlength` does not set the `minlength` attribute and therefore HTML5 constraint
 *     validation is not available.
 *   </li>
 *   <li>
 *     The `ngMinlength` value must be an expression, while the `minlength` value must be
 *     interpolated.

 *
 * @description
 *
 * ngAnimateChildren allows you to specify that children of this element should animate even if any
 * of the children's parents are currently animating. By default, when an element has an active `enter`, `leave`, or `move`
 * (structural) animation, child elements that also have an active structural animation are not animated.
 *
 * Note that even if `ngAnimateChildren` is set, no child animations will run when the parent element is removed from the DOM (`leave` animation).
 *
 *
 * @param {string} ngAnimateChildren If the value is empty, `true` or `on`,
 *     then child animations are allowed. If the value is `false`, child animations are not allowed.

/**
 * @ngdoc service
 * @name $animateCss
 * @kind object
 *
 * @description
 * The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
 * from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
 * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
 * directives to create more complex animations that can be purely driven using CSS code.
 *
 * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
 * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
 *
 * ## Usage
 * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
 * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
 * any automatic control over cancelling animations and/or preventing animations from being run on
 * child elements will not be handled by Angular. For this to work as expected, please use `$animate` to
 * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
 * the CSS animation.
 *
 * The example below shows how we can create a folding animation on an element using `ng-if`:
 *
 * ```html
 * <!-- notice the `fold-animation` CSS class -->
 * <div ng-if="onOff" class="fold-animation">
 *   This element will go BOOM
 * </div>
 * <button ng-click="onOff=true">Fold In</button>
 * ```
 *
 * Now we create the **JavaScript animation** that will trigger the CSS transition:
 *
 * ```js
 * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element, doneFn) {
 *       var height = element[0].offsetHeight;
 *       return $animateCss(element, {
 *         from: { height:'0px' },
 *         to: { height:height + 'px' },
 *         duration: 1 // one second
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * ## More Advanced Uses
 *
 * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
 * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
 *
 * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
 * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
 * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
 * to provide a working animation that will run in CSS.
 *
 * The example below showcases a more advanced version of the `.fold-animation` from the example above:
 *
 * ```js
 * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element, doneFn) {
 *       var height = element[0].offsetHeight;
 *       return $animateCss(element, {
 *         addClass: 'red large-text pulse-twice',
 *         easing: 'ease-out',
 *         from: { height:'0px' },
 *         to: { height:height + 'px' },
 *         duration: 1 // one second
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
 *
 * ```css
 * /&#42; since a hardcoded duration value of 1 was provided in the JavaScript animation code,
 * the CSS classes below will be transitioned despite them being defined as regular CSS classes &#42;/
 * .red { background:red; }
 * .large-text { font-size:20px; }
 *
 * /&#42; we can also use a keyframe animation and $animateCss will make it work alongside the transition &#42;/
 * .pulse-twice {
 *   animation: 0.5s pulse linear 2;
 *   -webkit-animation: 0.5s pulse linear 2;
 * }
 *
 * @keyframes pulse {
 *   from { transform: scale(0.5); }
 *   to { transform: scale(1.5); }
 * }
 *
 * @-webkit-keyframes pulse {
 *   from { -webkit-transform: scale(0.5); }
 *   to { -webkit-transform: scale(1.5); }
 * }
 * ```
 *
 * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
 *
 * ## How the Options are handled
 *
 * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
 * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline
 * styles using the `from` and `to` properties.
 *
 * ```js
 * var animator = $animateCss(element, {
 *   from: { background:'red' },
 *   to: { background:'blue' }
 * });
 * animator.start();
 * ```
 *
 * ```css
 * .rotating-animation {
 *   animation:0.5s rotate linear;
 *   -webkit-animation:0.5s rotate linear;
 * }
 *
 * @keyframes rotate {
 *   from { transform: rotate(0deg); }
 *   to { transform: rotate(360deg); }
 * }
 *
 * @-webkit-keyframes rotate {
 *   from { -webkit-transform: rotate(0deg); }
 *   to { -webkit-transform: rotate(360deg); }
 * }
 * ```
 *
 * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
 * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
 * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
 * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
 * and spread across the transition and keyframe animation.
 *
 * ## What is returned
 *
 * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
 * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
 * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
 *
 * ```js
 * var animator = $animateCss(element, { ... });
 * ```
 *
 * Now what do the contents of our `animator` variable look like:
 *
 * ```js
 * {
 *   // starts the animation
 *   start: Function,
 *
 *   // ends (aborts) the animation
 *   end: Function
 * }
 * ```
 *
 * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends.
 * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and styles may have been
 * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
 * and that changing them will not reconfigure the parameters of the animation.
 *
 * ### runner.done() vs runner.then()
 * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the
 * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
 * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
 * unless you really need a digest to kick off afterwards.
 *
 * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
 * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
 * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
 *
 * @param {DOMElement} element the element that will be animated
 * @param {object} options the animation-related options that will be applied during the animation
 *
 * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied
 * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.)
 * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and
 * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted.
 * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
 * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`).
 * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
 * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
 * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
 * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
 * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
 * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0`
 * is provided then the animation will be skipped entirely.
 * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is
 * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value
 * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same
 * CSS delay value.
 * * `stagger` - A numeric time value representing the delay between successively animated elements
 * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
 * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a
 *   `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
 * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occurring on the classes being added and removed.)
 * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once
 *    the animation is closed. This is useful for when the styles are used purely for the sake of
 *    the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation).
 *    By default this value is set to `false`.
 *
 * @return {object} an object with start and end methods and details about the animation.
 *
 * * `start` - The method to start the animation. This will return a `Promise` when called.
 * * `end` - This method will cancel the animation and remove all applied CSS classes and styles.

 *
 * ngAnimateSwap is a animation-oriented directive that allows for the container to
 * be removed and entered in whenever the associated expression changes. A
 * common usecase for this directive is a rotating banner or slider component which
 * contains one image being present at a time. When the active image changes
 * then the old image will perform a `leave` animation and the new element
 * will be inserted via an `enter` animation.

/**
 * @ngdoc module
 * @name ngAnimate
 * @description
 *
 * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
 * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an Angular app.
 *
 * <div doc-module-components="ngAnimate"></div>
 *
 * # Usage
 * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based
 * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
 * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
 * the HTML element that the animation will be triggered on.
 *
 * ## Directive Support
 * The following directives are "animation aware":
 *
 * | Directive                                                                                                | Supported Animations                                                     |
 * |----------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------|
 * | {@link ng.directive:ngRepeat#animations ngRepeat}                                                        | enter, leave and move                                                    |
 * | {@link ngRoute.directive:ngView#animations ngView}                                                       | enter and leave                                                          |
 * | {@link ng.directive:ngInclude#animations ngInclude}                                                      | enter and leave                                                          |
 * | {@link ng.directive:ngSwitch#animations ngSwitch}                                                        | enter and leave                                                          |
 * | {@link ng.directive:ngIf#animations ngIf}                                                                | enter and leave                                                          |
 * | {@link ng.directive:ngClass#animations ngClass}                                                          | add and remove (the CSS class(es) present)                               |
 * | {@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide}            | add and remove (the ng-hide class value)                                 |
 * | {@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel}    | add and remove (dirty, pristine, valid, invalid & all other validations) |
 * | {@link module:ngMessages#animations ngMessages}                                                          | add and remove (ng-active & ng-inactive)                                 |
 * | {@link module:ngMessages#animations ngMessage}                                                           | enter and leave                                                          |
 *

 *
 * ## CSS-based Animations
 *
 * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML
 * and CSS code we can create an animation that will be picked up by Angular when an underlying directive performs an operation.
 *
 * The example below shows how an `enter` animation can be made possible on an element using `ng-if`:
 *
 * ```html
 * <div ng-if="bool" class="fade">
 *    Fade me in out
 * </div>
 * <button ng-click="bool=true">Fade In!</button>
 * <button ng-click="bool=false">Fade Out!</button>
 * ```
 *
 * Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
 *
 * ```css
 * /&#42; The starting CSS styles for the enter animation &#42;/
 * .fade.ng-enter {
 *   transition:0.5s linear all;
 *   opacity:0;
 * }
 *
 * /&#42; The finishing CSS styles for the enter animation &#42;/
 * .fade.ng-enter.ng-enter-active {
 *   opacity:1;
 * }
 * ```
 *
 * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two
 * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition
 * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
 *
 * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions:
 *
 * ```css
 * /&#42; now the element will fade out before it is removed from the DOM &#42;/
 * .fade.ng-leave {
 *   transition:0.5s linear all;
 *   opacity:1;
 * }
 * .fade.ng-leave.ng-leave-active {
 *   opacity:0;
 * }
 * ```
 *
 * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
 *
 * ```css
 * /&#42; there is no need to define anything inside of the destination
 * CSS class since the keyframe will take charge of the animation &#42;/
 * .fade.ng-leave {
 *   animation: my_fade_animation 0.5s linear;
 *   -webkit-animation: my_fade_animation 0.5s linear;
 * }
 *
 * @keyframes my_fade_animation {
 *   from { opacity:1; }
 *   to { opacity:0; }
 * }
 *
 * @-webkit-keyframes my_fade_animation {
 *   from { opacity:1; }
 *   to { opacity:0; }
 * }
 * ```
 *
 * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
 *
 * ### CSS Class-based Animations
 *
 * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
 * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
 * and removed.
 *
 * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
 *
 * ```html
 * <div ng-show="bool" class="fade">
 *   Show and hide me
 * </div>
 * <button ng-click="bool=!bool">Toggle</button>
 *
 * <style>
 * .fade.ng-hide {
 *   transition:0.5s linear all;
 *   opacity:0;
 * }
 * </style>
 * ```
 *
 * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since
 * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
 *
 * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation
 * with CSS styles.
 *
 * ```html
 * <div ng-class="{on:onOff}" class="highlight">
 *   Highlight this box
 * </div>
 * <button ng-click="onOff=!onOff">Toggle</button>
 *
 * <style>
 * .highlight {
 *   transition:0.5s linear all;
 * }
 * .highlight.on-add {
 *   background:white;
 * }
 * .highlight.on {
 *   background:yellow;
 * }
 * .highlight.on-remove {
 *   background:black;
 * }
 * </style>
 * ```
 *
 * We can also make use of CSS keyframes by placing them within the CSS classes.
 *
 *
 * ### CSS Staggering Animations
 * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
 * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be
 * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
 * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
 * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
 *
 * ```css
 * .my-animation.ng-enter {
 *   /&#42; standard transition code &#42;/
 *   transition: 1s linear all;
 *   opacity:0;
 * }
 * .my-animation.ng-enter-stagger {
 *   /&#42; this will have a 100ms delay between each successive leave animation &#42;/
 *   transition-delay: 0.1s;
 *
 *   /&#42; As of 1.4.4, this must always be set: it signals ngAnimate
 *     to not accidentally inherit a delay property from another CSS class &#42;/
 *   transition-duration: 0s;
 * }
 * .my-animation.ng-enter.ng-enter-active {
 *   /&#42; standard transition styles &#42;/
 *   opacity:1;
 * }
 * ```
 *
 * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
 * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
 * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
 * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired.
 *
 * The following code will issue the **ng-leave-stagger** event on the element provided:
 *
 * ```js
 * var kids = parent.children();
 *
 * $animate.leave(kids[0]); //stagger index=0
 * $animate.leave(kids[1]); //stagger index=1
 * $animate.leave(kids[2]); //stagger index=2
 * $animate.leave(kids[3]); //stagger index=3
 * $animate.leave(kids[4]); //stagger index=4
 *
 * window.requestAnimationFrame(function() {
 *   //stagger has reset itself
 *   $animate.leave(kids[5]); //stagger index=0
 *   $animate.leave(kids[6]); //stagger index=1
 *
 *   $scope.$digest();
 * });
 * ```
 *
 * Stagger animations are currently only supported within CSS-defined animations.
 *
 * ### The `ng-animate` CSS class
 *
 * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
 * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
 *
 * Therefore, animations can be applied to an element using this temporary class directly via CSS.
 *
 * ```css
 * .zipper.ng-animate {
 *   transition:0.5s linear all;
 * }
 * .zipper.ng-enter {
 *   opacity:0;
 * }
 * .zipper.ng-enter.ng-enter-active {
 *   opacity:1;
 * }
 * .zipper.ng-leave {
 *   opacity:1;
 * }
 * .zipper.ng-leave.ng-leave-active {
 *   opacity:0;
 * }
 * ```
 *
 * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
 * the CSS class once an animation has completed.)
 *
 *
 * ### The `ng-[event]-prepare` class
 *
 * This is a special class that can be used to prevent unwanted flickering / flash of content before
 * the actual animation starts. The class is added as soon as an animation is initialized, but removed
 * before the actual animation starts (after waiting for a $digest).
 * It is also only added for *structural* animations (`enter`, `move`, and `leave`).
 *
 * In practice, flickering can appear when nesting elements with structural animations such as `ngIf`
 * into elements that have class-based animations such as `ngClass`.
 *
 * ```html
 * <div ng-class="{red: myProp}">
 *   <div ng-class="{blue: myProp}">
 *     <div class="message" ng-if="myProp"></div>
 *   </div>
 * </div>
 * ```
 *
 * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating.
 * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts:
 *
 * ```css
 * .message.ng-enter-prepare {
 *   opacity: 0;
 * }
 *
 * ```
 *
 * ## JavaScript-based Animations
 *
 * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
 * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the
 * `module.animation()` module function we can register the animation.
 *
 * Let's see an example of a enter/leave animation using `ngRepeat`:
 *
 * ```html
 * <div ng-repeat="item in items" class="slide">
 *   {{ item }}
 * </div>
 * ```
 *
 * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`:
 *
 * ```js
 * myModule.animation('.slide', [function() {
 *   return {
 *     // make note that other events (like addClass/removeClass)
 *     // have different function input parameters
 *     enter: function(element, doneFn) {
 *       jQuery(element).fadeIn(1000, doneFn);
 *
 *       // remember to call doneFn so that angular
 *       // knows that the animation has concluded
 *     },
 *
 *     move: function(element, doneFn) {
 *       jQuery(element).fadeIn(1000, doneFn);
 *     },
 *
 *     leave: function(element, doneFn) {
 *       jQuery(element).fadeOut(1000, doneFn);
 *     }
 *   }
 * }]);
 * ```
 *
 * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as
 * greensock.js and velocity.js.
 *
 * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define
 * our animations inside of the same registered animation, however, the function input arguments are a bit different:
 *
 * ```html
 * <div ng-class="color" class="colorful">
 *   this box is moody
 * </div>
 * <button ng-click="color='red'">Change to red</button>
 * <button ng-click="color='blue'">Change to blue</button>
 * <button ng-click="color='green'">Change to green</button>
 * ```
 *
 * ```js
 * myModule.animation('.colorful', [function() {
 *   return {
 *     addClass: function(element, className, doneFn) {
 *       // do some cool animation and call the doneFn
 *     },
 *     removeClass: function(element, className, doneFn) {
 *       // do some cool animation and call the doneFn
 *     },
 *     setClass: function(element, addedClass, removedClass, doneFn) {
 *       // do some cool animation and call the doneFn
 *     }
 *   }
 * }]);
 * ```
 *
 * ## CSS + JS Animations Together
 *
 * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of Angular,
 * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking
 * charge of the animation**:
 *
 * ```html
 * <div ng-if="bool" class="slide">
 *   Slide in and out
 * </div>
 * ```
 *
 * ```js
 * myModule.animation('.slide', [function() {
 *   return {
 *     enter: function(element, doneFn) {
 *       jQuery(element).slideIn(1000, doneFn);
 *     }
 *   }
 * }]);
 * ```
 *
 * ```css
 * .slide.ng-enter {
 *   transition:0.5s linear all;
 *   transform:translateY(-100px);
 * }
 * .slide.ng-enter.ng-enter-active {
 *   transform:translateY(0);
 * }
 * ```
 *
 * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the
 * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
 * our own JS-based animation code:
 *
 * ```js
 * myModule.animation('.slide', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element) {
*        // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
 *       return $animateCss(element, {
 *         event: 'enter',
 *         structural: true
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
 *
 * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or
 * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that
 * data into `$animateCss` directly:
 *
 * ```js
 * myModule.animation('.slide', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element) {
 *       return $animateCss(element, {
 *         event: 'enter',
 *         structural: true,
 *         addClass: 'maroon-setting',
 *         from: { height:0 },
 *         to: { height: 200 }
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * Now we can fill in the rest via our transition CSS code:
 *
 * ```css
 * /&#42; the transition tells ngAnimate to make the animation happen &#42;/
 * .slide.ng-enter { transition:0.5s linear all; }
 *
 * /&#42; this extra CSS class will be absorbed into the transition
 * since the $animateCss code is adding the class &#42;/
 * .maroon-setting { background:red; }
 * ```
 *
 * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over.
 *
 * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}.
 *
 * ## Animation Anchoring (via `ng-animate-ref`)
 *
 * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
 * structural areas of an application (like views) by pairing up elements using an attribute
 * called `ng-animate-ref`.
 *
 * Let's say for example we have two views that are managed by `ng-view` and we want to show
 * that there is a relationship between two components situated in within these views. By using the
 * `ng-animate-ref` attribute we can identify that the two components are paired together and we
 * can then attach an animation, which is triggered when the view changes.
 *
 * Say for example we have the following template code:
 *
 * ```html
 * <!-- index.html -->
 * <div ng-view class="view-animation">
 * </div>
 *
 * <!-- home.html -->
 * <a href="#/banner-page">
 *   <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
 * </a>
 *
 * <!-- banner-page.html -->
 * <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
 * ```
 *
 * Now, when the view changes (once the link is clicked), ngAnimate will examine the
 * HTML contents to see if there is a match reference between any components in the view
 * that is leaving and the view that is entering. It will scan both the view which is being
 * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
 * contain a matching ref value.
 *
 * The two images match since they share the same ref value. ngAnimate will now create a
 * transport element (which is a clone of the first image element) and it will then attempt
 * to animate to the position of the second image element in the next view. For the animation to
 * work a special CSS class called `ng-anchor` will be added to the transported element.
 *
 * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
 * ngAnimate will handle the entire transition for us as well as the addition and removal of
 * any changes of CSS classes between the elements:
 *
 * ```css
 * .banner.ng-anchor {
 *   /&#42; this animation will last for 1 second since there are
 *          two phases to the animation (an `in` and an `out` phase) &#42;/
 *   transition:0.5s linear all;
 * }
 * ```
 *
 * We also **must** include animations for the views that are being entered and removed
 * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
 *
 * ```css
 * .view-animation.ng-enter, .view-animation.ng-leave {
 *   transition:0.5s linear all;
 *   position:fixed;
 *   left:0;
 *   top:0;
 *   width:100%;
 * }
 * .view-animation.ng-enter {
 *   transform:translateX(100%);
 * }
 * .view-animation.ng-leave,
 * .view-animation.ng-enter.ng-enter-active {
 *   transform:translateX(0%);
 * }
 * .view-animation.ng-leave.ng-leave-active {
 *   transform:translateX(-100%);
 * }
 * ```
 *
 * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
 * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
 * from its origin. Once that animation is over then the `in` stage occurs which animates the
 * element to its destination. The reason why there are two animations is to give enough time
 * for the enter animation on the new element to be ready.
 *
 * The example above sets up a transition for both the in and out phases, but we can also target the out or
 * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
 *
 * ```css
 * .banner.ng-anchor-out {
 *   transition: 0.5s linear all;
 *
 *   /&#42; the scale will be applied during the out animation,
 *          but will be animated away when the in animation runs &#42;/
 *   transform: scale(1.2);
 * }
 *
 * .banner.ng-anchor-in {
 *   transition: 1s linear all;
 * }
 * ```
 *
 *
 *

 *
 * ### How is the element transported?
 *
 * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
 * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
 * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
 * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
 * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
 * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
 * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
 * will become visible since the shim class will be removed.
 *
 * ### How is the morphing handled?
 *
 * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
 * what CSS classes differ between the starting element and the destination element. These different CSS classes
 * will be added/removed on the anchor element and a transition will be applied (the transition that is provided
 * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
 * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
 * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
 * the cloned element is placed inside of root element which is likely close to the body element).
 *
 * Note that if the root element is on the `<html>` element then the cloned node will be placed inside of body.
 *
 *
 * ## Using $animate in your directive code
 *
 * So far we've explored how to feed in animations into an Angular application, but how do we trigger animations within our own directives in our application?
 * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
 * imagine we have a greeting box that shows and hides itself when the data changes
 *
 * ```html
 * <greeting-box active="onOrOff">Hi there</greeting-box>
 * ```
 *
 * ```js
 * ngModule.directive('greetingBox', ['$animate', function($animate) {
 *   return function(scope, element, attrs) {
 *     attrs.$observe('active', function(value) {
 *       value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
 *     });
 *   });
 * }]);
 * ```
 *
 * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
 * in our HTML code then we can trigger a CSS or JS animation to happen.
 *
 * ```css
 * /&#42; normally we would create a CSS class to reference on the element &#42;/
 * greeting-box.on { transition:0.5s linear all; background:green; color:white; }
 * ```
 *
 * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
 * possible be sure to visit the {@link ng.$animate $animate service API page}.
 *
 *
 * ## Callbacks and Promises
 *
 * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
 * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
 * ended by chaining onto the returned promise that animation method returns.
 *
 * ```js
 * // somewhere within the depths of the directive
 * $animate.enter(element, parent).then(function() {
 *   //the animation has completed
 * });
 * ```
 *
 * (Note that earlier versions of Angular prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
 * anymore.)
 *
 * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
 * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
 * routing controller to hook into that:
 *
 * ```js
 * ngModule.controller('HomePageController', ['$animate', function($animate) {
 *   $animate.on('enter', ngViewElement, function(element) {
 *     // the animation for this route has completed
 *   }]);
 * }])
 * ```
 *
 * (Note that you will need to trigger a digest within the callback to get angular to notice any scope-related changes.)

 *
 * The `ngAria` module provides support for common

 *
 * <div doc-module-components="ngAria"></div>
 *
 * ## Usage
 *
 * For ngAria to do its magic, simply include the module `ngAria` as a dependency. The following
 * directives are supported:
 * `ngModel`, `ngChecked`, `ngReadonly`, `ngRequired`, `ngValue`, `ngDisabled`, `ngShow`, `ngHide`, `ngClick`,
 * `ngDblClick`, and `ngMessages`.
 *
 * Below is a more detailed breakdown of the attributes handled by ngAria:
 *
 * | Directive                                   | Supported Attributes                                                                   |

 * | {@link ng.directive:ngReadonly ngReadonly}  | aria-readonly                                                                          |
 * | {@link ng.directive:ngValue ngValue}        | aria-checked                                                                           |
 * | {@link ng.directive:ngShow ngShow}          | aria-hidden                                                                            |
 * | {@link ng.directive:ngHide ngHide}          | aria-hidden                                                                            |
 * | {@link ng.directive:ngDblclick ngDblclick}  | tabindex                                                                               |
 * | {@link module:ngMessages ngMessages}        | aria-live                                                                              |
 * | {@link ng.directive:ngClick ngClick}        | tabindex, keypress event, button role                                                  |
 *
 * Find out more information about each directive by reading the
 * {@link guide/accessibility ngAria Developer Guide}.
 *
 * ## Example
 * Using ngDisabled with ngAria:
 * ```html
 * <md-checkbox ng-disabled="disabled">
 * ```
 * Becomes:
 * ```html
 * <md-checkbox ng-disabled="disabled" aria-disabled="true">
 * ```
 *
 * ## Disabling Attributes
 * It's possible to disable individual attributes added by ngAria with the
 * {@link ngAria.$ariaProvider#config config} method. For more details, see the

   *
   * The $aria service contains helper methods for applying common
   * [ARIA](http://www.w3.org/TR/wai-aria/) attributes to HTML directives.
   *
   * ngAria injects common accessibility attributes that tell assistive technologies when HTML
   * elements are enabled, selected, hidden, and more. To see how this is performed with ngAria,
   * let's review a code snippet from ngAria itself:
   *
   *```js
   * ngAriaModule.directive('ngDisabled', ['$aria', function($aria) {
   *   return $aria.$$watchExpr('ngDisabled', 'aria-disabled', nodeBlackList, false);
   * }])
   *```
   * Shown above, the ngAria module creates a directive with the same signature as the
   * traditional `ng-disabled` directive. But this ngAria version is dedicated to
   * solely managing accessibility attributes on custom elements. The internal `$aria` service is
   * used to watch the boolean attribute `ngDisabled`. If it has not been explicitly set by the
   * developer, `aria-disabled` is injected as an attribute with its value synchronized to the
   * value in `ngDisabled`.
   *
   * Because ngAria hooks into the `ng-disabled` directive, developers do not have to do
   * anything to enable this feature. The `aria-disabled` attribute is automatically managed
   * simply as a silent side-effect of using `ng-disabled` with the ngAria module.
   *
   * The full list of directives that interface with ngAria:
   * * **ngModel**
   * * **ngChecked**
   * * **ngReadonly**
   * * **ngRequired**
   * * **ngDisabled**
   * * **ngValue**
   * * **ngShow**
   * * **ngHide**
   * * **ngClick**
   * * **ngDblclick**
   * * **ngMessages**
   *
   * Read the {@link guide/accessibility ngAria Developer Guide} for a thorough explanation of each
   * directive.

/**
 * @ngdoc module
 * @name ngMessages
 * @description
 *
 * The `ngMessages` module provides enhanced support for displaying messages within templates
 * (typically within forms or when rendering message objects that return key/value data).
 * Instead of relying on JavaScript code and/or complex ng-if statements within your form template to
 * show and hide error messages specific to the state of an input field, the `ngMessages` and
 * `ngMessage` directives are designed to handle the complexity, inheritance and priority
 * sequencing based on the order of how the messages are defined in the template.
 *
 * Currently, the ngMessages module only contains the code for the `ngMessages`, `ngMessagesInclude`
 * `ngMessage` and `ngMessageExp` directives.
 *
 * # Usage
 * The `ngMessages` directive allows keys in a key/value collection to be associated with a child element
 * (or 'message') that will show or hide based on the truthiness of that key's value in the collection. A common use
 * case for `ngMessages` is to display error messages for inputs using the `$error` object exposed by the
 * {@link ngModel ngModel} directive.
 *
 * The child elements of the `ngMessages` directive are matched to the collection keys by a `ngMessage` or
 * `ngMessageExp` directive. The value of these attributes must match a key in the collection that is provided by
 * the `ngMessages` directive.
 *
 * Consider the following example, which illustrates a typical use case of `ngMessages`. Within the form `myForm` we
 * have a text input named `myField` which is bound to the scope variable `field` using the {@link ngModel ngModel}
 * directive.
 *
 * The `myField` field is a required input of type `email` with a maximum length of 15 characters.
 *
 * ```html
 * <form name="myForm">
 *   <label>
 *     Enter text:
 *     <input type="email" ng-model="field" name="myField" required maxlength="15" />
 *   </label>
 *   <div ng-messages="myForm.myField.$error" role="alert">
 *     <div ng-message="required">Please enter a value for this field.</div>
 *     <div ng-message="email">This field must be a valid email address.</div>
 *     <div ng-message="maxlength">This field can be at most 15 characters long.</div>
 *   </div>
 * </form>
 * ```
 *
 * In order to show error messages corresponding to `myField` we first create an element with an `ngMessages` attribute
 * set to the `$error` object owned by the `myField` input in our `myForm` form.
 *
 * Within this element we then create separate elements for each of the possible errors that `myField` could have.
 * The `ngMessage` attribute is used to declare which element(s) will appear for which error - for example,
 * setting `ng-message="required"` specifies that this particular element should be displayed when there
 * is no value present for the required field `myField` (because the key `required` will be `true` in the object
 * `myForm.myField.$error`).
 *
 * ### Message order
 *
 * By default, `ngMessages` will only display one message for a particular key/value collection at any time. If more
 * than one message (or error) key is currently true, then which message is shown is determined by the order of messages
 * in the HTML template code (messages declared first are prioritised). This mechanism means the developer does not have
 * to prioritize messages using custom JavaScript code.
 *
 * Given the following error object for our example (which informs us that the field `myField` currently has both the
 * `required` and `email` errors):
 *
 * ```javascript
 * <!-- keep in mind that ngModel automatically sets these error flags -->
 * myField.$error = { required : true, email: true, maxlength: false };
 * ```
 * The `required` message will be displayed to the user since it appears before the `email` message in the DOM.
 * Once the user types a single character, the `required` message will disappear (since the field now has a value)
 * but the `email` message will be visible because it is still applicable.
 *
 * ### Displaying multiple messages at the same time
 *
 * While `ngMessages` will by default only display one error element at a time, the `ng-messages-multiple` attribute can
 * be applied to the `ngMessages` container element to cause it to display all applicable error messages at once:
 *
 * ```html
 * <!-- attribute-style usage -->
 * <div ng-messages="myForm.myField.$error" ng-messages-multiple>...</div>
 *
 * <!-- element-style usage -->
 * <ng-messages for="myForm.myField.$error" multiple>...</ng-messages>
 * ```
 *
 * ## Reusing and Overriding Messages
 * In addition to prioritization, ngMessages also allows for including messages from a remote or an inline
 * template. This allows for generic collection of messages to be reused across multiple parts of an
 * application.
 *
 * ```html
 * <script type="text/ng-template" id="error-messages">
 *   <div ng-message="required">This field is required</div>
 *   <div ng-message="minlength">This field is too short</div>
 * </script>
 *
 * <div ng-messages="myForm.myField.$error" role="alert">
 *   <div ng-messages-include="error-messages"></div>
 * </div>
 * ```
 *
 * However, including generic messages may not be useful enough to match all input fields, therefore,
 * `ngMessages` provides the ability to override messages defined in the remote template by redefining
 * them within the directive container.
 *
 * ```html
 * <!-- a generic template of error messages known as "my-custom-messages" -->
 * <script type="text/ng-template" id="my-custom-messages">
 *   <div ng-message="required">This field is required</div>
 *   <div ng-message="minlength">This field is too short</div>
 * </script>
 *
 * <form name="myForm">
 *   <label>
 *     Email address
 *     <input type="email"
 *            id="email"
 *            name="myEmail"
 *            ng-model="email"
 *            minlength="5"
 *            required />
 *   </label>
 *   <!-- any ng-message elements that appear BEFORE the ng-messages-include will
 *        override the messages present in the ng-messages-include template -->
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <!-- this required message has overridden the template message -->
 *     <div ng-message="required">You did not enter your email address</div>
 *
 *     <!-- this is a brand new message and will appear last in the prioritization -->
 *     <div ng-message="email">Your email address is invalid</div>
 *
 *     <!-- and here are the generic error messages -->
 *     <div ng-messages-include="my-custom-messages"></div>
 *   </div>
 * </form>
 * ```
 *
 * In the example HTML code above the message that is set on required will override the corresponding
 * required message defined within the remote template. Therefore, with particular input fields (such
 * email addresses, date fields, autocomplete inputs, etc...), specialized error messages can be applied
 * while more generic messages can be used to handle other, more general input errors.
 *
 * ## Dynamic Messaging
 * ngMessages also supports using expressions to dynamically change key values. Using arrays and
 * repeaters to list messages is also supported. This means that the code below will be able to
 * fully adapt itself and display the appropriate message when any of the expression data changes:
 *
 * ```html
 * <form name="myForm">
 *   <label>
 *     Email address
 *     <input type="email"
 *            name="myEmail"
 *            ng-model="email"
 *            minlength="5"
 *            required />
 *   </label>
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <div ng-message="required">You did not enter your email address</div>
 *     <div ng-repeat="errorMessage in errorMessages">
 *       <!-- use ng-message-exp for a message whose key is given by an expression -->
 *       <div ng-message-exp="errorMessage.type">{{ errorMessage.text }}</div>
 *     </div>
 *   </div>
 * </form>
 * ```
 *
 * The `errorMessage.type` expression can be a string value or it can be an array so
 * that multiple errors can be associated with a single error message:
 *
 * ```html
 *   <label>
 *     Email address
 *     <input type="email"
 *            ng-model="data.email"
 *            name="myEmail"
 *            ng-minlength="5"
 *            ng-maxlength="100"
 *            required />
 *   </label>
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <div ng-message-exp="'required'">You did not enter your email address</div>
 *     <div ng-message-exp="['minlength', 'maxlength']">
 *       Your email must be between 5 and 100 characters long
 *     </div>
 *   </div>
 * ```
 *
 * Feel free to use other structural directives such as ng-if and ng-switch to further control
 * what messages are active and when. Be careful, if you place ng-message on the same element
 * as these structural directives, Angular may not be able to determine if a message is active
 * or not. Therefore it is best to place the ng-message on a child element of the structural
 * directive.
 *
 * ```html
 * <div ng-messages="myForm.myEmail.$error" role="alert">
 *   <div ng-if="showRequiredError">
 *     <div ng-message="required">Please enter something</div>
 *   </div>
 * </div>
 * ```
 *
 * ## Animations
 * If the `ngAnimate` module is active within the application then the `ngMessages`, `ngMessage` and
 * `ngMessageExp` directives will trigger animations whenever any messages are added and removed from
 * the DOM by the `ngMessages` directive.
 *
 * Whenever the `ngMessages` directive contains one or more visible messages then the `.ng-active` CSS
 * class will be added to the element. The `.ng-inactive` CSS class will be applied when there are no
 * messages present. Therefore, CSS transitions and keyframes as well as JavaScript animations can
 * hook into the animations whenever these classes are added/removed.
 *
 * Let's say that our HTML code for our messages container looks like so:
 *
 * ```html
 * <div ng-messages="myMessages" class="my-messages" role="alert">
 *   <div ng-message="alert" class="some-message">...</div>
 *   <div ng-message="fail" class="some-message">...</div>
 * </div>
 * ```
 *
 * Then the CSS animation code for the message container looks like so:
 *
 * ```css
 * .my-messages {
 *   transition:1s linear all;
 * }
 * .my-messages.ng-active {
 *   // messages are visible
 * }
 * .my-messages.ng-inactive {
 *   // messages are hidden
 * }
 * ```
 *
 * Whenever an inner message is attached (becomes visible) or removed (becomes hidden) then the enter
 * and leave animation is triggered for each particular element bound to the `ngMessage` directive.
 *
 * Therefore, the CSS code for the inner messages looks like so:
 *
 * ```css
 * .some-message {
 *   transition:1s linear all;
 * }
 *
 * .some-message.ng-enter {}
 * .some-message.ng-enter.ng-enter-active {}
 *
 * .some-message.ng-leave {}
 * .some-message.ng-leave.ng-leave-active {}
 * ```

   * @description
   * `ngMessages` is a directive that is designed to show and hide messages based on the state
   * of a key/value object that it listens on. The directive itself complements error message
   * reporting with the `ngModel` $error object (which stores a key/value state of validation errors).
   *
   * `ngMessages` manages the state of internal messages within its container element. The internal
   * messages use the `ngMessage` directive and will be inserted/removed from the page depending
   * on if they're present within the key/value object. By default, only one message will be displayed
   * at a time and this depends on the prioritization of the messages within the template. (This can
   * be changed by using the `ng-messages-multiple` or `multiple` attribute on the directive container.)
   *
   * A remote template can also be used to promote message reusability and messages can also be
   * overridden.

    *      return a a new string representing the transformed template.
    *    - `resolve` - `{Object.<string, function>=}` - An optional map of dependencies which should

    *      will wait for them all to be resolved, or if one is rejected before the controller is

    *   - `locals` - `{object}`: The locals which will be passed into the controller once `link` is
    *     called. If `bindToController` is true, they will be coppied to the ctrl instead
    *   - `bindToController` - `bool`: bind the locals to the controller, instead of passing them in.

 * ### Default Theme
 * The `$mdThemingProvider` uses by default the following theme configuration:
 *
 * - Primary Palette: `Primary`
 * - Accent Palette: `Pink`
 * - Warn Palette: `Deep-Orange`
 * - Background Palette: `Grey`
 *
 * If you don't want to use the `md-theme` directive on the elements itself, you may want to overwrite
 * the default theme.<br/>
 * This can be done by using the following markup.
 *
 * <hljs lang="js">
 *   myAppModule.config(function($mdThemingProvider) {
 *     $mdThemingProvider
 *       .theme('default')
 *       .primaryPalette('blue')
 *       .accentPalette('teal')
 *       .warnPalette('red')
 *       .backgroundPalette('grey');
 *   });
 * </hljs>
 *

 * ### Dynamic Themes
 *
 * By default, if you change a theme at runtime, the `$mdTheming` service will not detect those changes.<br/>
 * If you have an application, which changes its theme on runtime, you have to enable theme watching.

 *
 * ### Custom Theme Styles
 *
 * Sometimes you may want to use your own theme styles for some custom components.<br/>
 * You are able to register your own styles by using the following markup.
 *
 * <hljs lang="js">
 *   myAppModule.config(function($mdThemingProvider) {
 *     // Register our custom stylesheet into the theming provider.
 *     $mdThemingProvider.registerStyles(STYLESHEET);
 *   });
 * </hljs>
 *
 * The `registerStyles` method only accepts strings as value, so you're actually not able to load an external
 * stylesheet file into the `$mdThemingProvider`.
 *
 * If it's necessary to load an external stylesheet, we suggest using a bundler, which supports including raw content,
 * like [raw-loader](https://github.com/webpack/raw-loader) for `webpack`.
 *
 * <hljs lang="js">
 *   myAppModule.config(function($mdThemingProvider) {
 *     // Register your custom stylesheet into the theming provider.
 *     $mdThemingProvider.registerStyles(require('../styles/my-component.theme.css'));
 *   });
 * </hljs>
 *
 * ### Browser color
 *
 * Enables browser header coloring
 * for more info please visit:
 * https://developers.google.com/web/fundamentals/design-and-ui/browser-customization/theme-color
 *
 * Options parameter: <br/>
 * `theme`   - A defined theme via `$mdThemeProvider` to use the palettes from. Default is `default` theme. <br/>
 * `palette` - Can be any one of the basic material design palettes, extended defined palettes and 'primary',
 *             'accent', 'background' and 'warn'. Default is `primary`. <br/>
 * `hue`     - The hue from the selected palette. Default is `800`<br/>
 *
 * <hljs lang="js">
 *   myAppModule.config(function($mdThemingProvider) {
 *     // Enable browser color
 *     $mdThemingProvider.enableBrowserColor({
 *       theme: 'myTheme', // Default is 'default'

/* Some Example Valid Theming Expressions
 * =======================================
 *
 * Intention group expansion: (valid for primary, accent, warn, background)
 *
 * {{primary-100}} - grab shade 100 from the primary palette
 * {{primary-100-0.7}} - grab shade 100, apply opacity of 0.7
 * {{primary-100-contrast}} - grab shade 100's contrast color
 * {{primary-hue-1}} - grab the shade assigned to hue-1 from the primary palette
 * {{primary-hue-1-0.7}} - apply 0.7 opacity to primary-hue-1
 * {{primary-color}} - Generates .md-hue-1, .md-hue-2, .md-hue-3 with configured shades set for each hue
 * {{primary-color-0.7}} - Apply 0.7 opacity to each of the above rules
 * {{primary-contrast}} - Generates .md-hue-1, .md-hue-2, .md-hue-3 with configured contrast (ie. text) color shades set for each hue
 * {{primary-contrast-0.7}} - Apply 0.7 opacity to each of the above rules
 *
 * Foreground expansion: Applies rgba to black/white foreground text
 *
 * {{foreground-1}} - used for primary text
 * {{foreground-2}} - used for secondary text/divider
 * {{foreground-3}} - used for disabled text
 * {{foreground-4}} - used for dividers

 *   be used as the content of the bottom sheet. Restrictions: the template must
 *   have an outer `md-bottom-sheet` element.
 *   - `template` - `{string=}`: Same as templateUrl, except this is an actual
 *   template string.
 *   - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified, it will create a new child scope.
 *     This scope will be destroyed when the bottom sheet is removed unless `preserveScope` is set to true.
 *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
 *   - `controller` - `{string=}`: The controller to associate with this bottom sheet.
 *   - `locals` - `{string=}`: An object containing key/value pairs. The keys will
 *   be used as names of values to inject into the controller. For example,
 *   `locals: {three: 3}` would inject `three` into the controller with the value
 *   of 3.
 *   - `clickOutsideToClose` - `{boolean=}`: Whether the user can click outside the bottom sheet to
 *     close it. Default true.
 *   - `disableBackdrop` - `{boolean=}`: When set to true, the bottomsheet will not show a backdrop.
 *   - `escapeToClose` - `{boolean=}`: Whether the user can press escape to close the bottom sheet.
 *     Default true.
 *   - `resolve` - `{object=}`: Similar to locals, except it takes promises as values
 *   and the bottom sheet will not open until the promises resolve.
 *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
 *   - `parent` - `{element=}`: The element to append the bottom sheet to. The `parent` may be a `function`, `string`,
 *   `object`, or null. Defaults to appending to the body of the root element (or the root element) of the application.
 *   e.g. angular.element(document.getElementById('content')) or "#content"
 *   - `disableParentScroll` - `{boolean=}`: Whether to disable scrolling while the bottom sheet is open.

 * rejected with `$mdBottomSheet.cancel()`.

 * Developers can also change the color palette of the button, by using the following classes
 * - `md-primary`
 * - `md-accent`
 * - `md-warn`
 *
 * See for example
 *
 * <hljs lang="html">

 *
 * It is also possible to disable the focus effect on the button, by using the following markup.

 * * `<md-card-header>` - Header for the card, holds avatar, text and squared image
 *  - `<md-card-avatar>` - Card avatar
 *    - `md-user-avatar` - Class for user image

 * * `<md-card-title>` - Card content title
 *  - `<md-card-title-text>`

 *
 * @description
 *
 * The `<md-content>` directive is a container element useful for scrollable content. It achieves
 * this by setting the CSS `overflow` property to `auto` so that content can properly scroll.
 *
 * In general, `<md-content>` components are not designed to be nested inside one another. If
 * possible, it is better to make them siblings. This often results in a better user experience as
 * having nested scrollbars may confuse the user.
 *
 * ## Troubleshooting
 *
 * In some cases, you may wish to apply the `md-no-momentum` class to ensure that Safari's
 * momentum scrolling is disabled. Momentum scrolling can cause flickering issues while scrolling
 * SVG icons and some other components.
 *
 * Additionally, we now also offer the `md-no-flicker` class which can be applied to any element
 * and uses a Webkit-specific filter of `blur(0px)` that forces GPU rendering of all elements
 * inside (which eliminates the flicker on iOS devices).
 *
 * _<b>Note:</b> Forcing an element to render on the GPU can have unintended side-effects, especially
 * related to the z-index of elements. Please use with caution and only on the elements needed._
 *
 * @usage
 *
 * Add the `[layout-padding]` attribute to make the content padded.

/**
 * @ngdoc service
 * @name $mdDialog
 * @module material.components.dialog
 *
 * @description
 * `$mdDialog` opens a dialog over the app to inform users about critical information or require
 *  them to make decisions. There are two approaches for setup: a simple promise API
 *  and regular object syntax.
 *
 * ## Restrictions
 *
 * - The dialog is always given an isolate scope.
 * - The dialog's template must have an outer `<md-dialog>` element.
 *   Inside, use an `<md-dialog-content>` element for the dialog's content, and use
 *   an `<md-dialog-actions>` element for the dialog's actions.
 * - Dialogs must cover the entire application to keep interactions inside of them.
 * Use the `parent` option to change where dialogs are appended.
 *
 * ## Sizing
 * - Complex dialogs can be sized with `flex="percentage"`, i.e. `flex="66"`.
 * - Default max-width is 80% of the `rootElement` or `parent`.
 *
 * ## CSS
 * - `.md-dialog-content` - class that sets the padding on the content as the spec file
 *

 *         }
 *       }
 *     }
 *   }
 * })(angular);
 * </hljs>
 *
 * ### Pre-Rendered Dialogs
 * By using the `contentElement` option, it is possible to use an already existing element in the DOM.
 *
 * <hljs lang="js">
 *   $scope.showPrerenderedDialog = function() {
 *     $mdDialog.show({
 *       contentElement: '#myStaticDialog',
 *       parent: angular.element(document.body)
 *     });
 *   };
 * </hljs>
 *
 * When using a string as value, `$mdDialog` will automatically query the DOM for the specified CSS selector.
 *
 * <hljs lang="html">
 *   <div style="visibility: hidden">
 *     <div class="md-dialog-container" id="myStaticDialog">
 *       <md-dialog>
 *         This is a pre-rendered dialog.
 *       </md-dialog>
 *     </div>
 *   </div>
 * </hljs>
 *
 * **Notice**: It is important, to use the `.md-dialog-container` as the content element, otherwise the dialog
 * will not show up.
 *
 * It also possible to use a DOM element for the `contentElement` option.
 * - `contentElement: document.querySelector('#myStaticDialog')`
 * - `contentElement: angular.element(TEMPLATE)`
 *
 * When using a `template` as content element, it will be not compiled upon open.
 * This allows you to compile the element yourself and use it each time the dialog opens.
 *
 * ### Custom Presets
 * Developers are also able to create their own preset, which can be easily used without repeating
 * their options each time.
 *
 * <hljs lang="js">
 *   $mdDialogProvider.addPreset('testPreset', {
 *     options: function() {
 *       return {
 *         template:
 *           '<md-dialog>' +
 *             'This is a custom preset' +
 *           '</md-dialog>',
 *         controllerAs: 'dialog',
 *         bindToController: true,
 *         clickOutsideToClose: true,
 *         escapeToClose: true
 *       };
 *     }
 *   });
 * </hljs>
 *
 * After you created your preset at config phase, you can easily access it.
 *
 * <hljs lang="js">
 *   $mdDialog.show(
 *     $mdDialog.testPreset()
 *   );
 * </hljs>
 *

/**
 * @ngdoc method
 * @name $mdDialog#show
 *
 * @description
 * Show a dialog with the specified options.
 *
 * @param {object} optionsOrPreset Either provide an `$mdDialogPreset` returned from `alert()`, and
 * `confirm()`, or an options object with the following properties:
 *   - `templateUrl` - `{string=}`: The url of a template that will be used as the content
 *   of the dialog.
 *   - `template` - `{string=}`: HTML template to show in the dialog. This **must** be trusted HTML
 *      with respect to Angular's [$sce service](https://docs.angularjs.org/api/ng/service/$sce).
 *      This template should **never** be constructed with any kind of user input or user data.
 *   - `contentElement` - `{string|Element}`: Instead of using a template, which will be compiled each time a
 *     dialog opens, you can also use a DOM element.<br/>
 *     * When specifying an element, which is present on the DOM, `$mdDialog` will temporary fetch the element into
 *       the dialog and restores it at the old DOM position upon close.
 *     * When specifying a string, the string be used as a CSS selector, to lookup for the element in the DOM.
 *   - `autoWrap` - `{boolean=}`: Whether or not to automatically wrap the template with a
 *     `<md-dialog>` tag if one is not provided. Defaults to true. Can be disabled if you provide a
 *     custom dialog directive.
 *   - `targetEvent` - `{DOMClickEvent=}`: A click's event object. When passed in as an option,
 *     the location of the click will be used as the starting point for the opening animation
 *     of the the dialog.
 *   - `openFrom` - `{string|Element|object}`: The query selector, DOM element or the Rect object
 *     that is used to determine the bounds (top, left, height, width) from which the Dialog will
 *     originate.
 *   - `closeTo` - `{string|Element|object}`: The query selector, DOM element or the Rect object
 *     that is used to determine the bounds (top, left, height, width) to which the Dialog will
 *     target.
 *   - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified,
 *     it will create a new isolate scope.
 *     This scope will be destroyed when the dialog is removed unless `preserveScope` is set to true.
 *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
 *   - `disableParentScroll` - `{boolean=}`: Whether to disable scrolling while the dialog is open.
 *     Default true.
 *   - `hasBackdrop` - `{boolean=}`: Whether there should be an opaque backdrop behind the dialog.
 *     Default true.
 *   - `clickOutsideToClose` - `{boolean=}`: Whether the user can click outside the dialog to
 *     close it. Default false.
 *   - `escapeToClose` - `{boolean=}`: Whether the user can press escape to close the dialog.
 *     Default true.
 *   - `focusOnOpen` - `{boolean=}`: An option to override focus behavior on open. Only disable if
 *     focusing some other way, as focus management is required for dialogs to be accessible.
 *     Defaults to true.
 *   - `controller` - `{function|string=}`: The controller to associate with the dialog. The controller
 *     will be injected with the local `$mdDialog`, which passes along a scope for the dialog.
 *   - `locals` - `{object=}`: An object containing key/value pairs. The keys will be used as names
 *     of values to inject into the controller. For example, `locals: {three: 3}` would inject
 *     `three` into the controller, with the value 3. If `bindToController` is true, they will be
 *     copied to the controller instead.
 *   - `bindToController` - `bool`: bind the locals to the controller, instead of passing them in.
 *   - `resolve` - `{object=}`: Similar to locals, except it takes promises as values, and the
 *     dialog will not open until all of the promises resolve.
 *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
 *   - `parent` - `{element=}`: The element to append the dialog to. Defaults to appending
 *     to the root element of the application.
 *   - `onShowing` - `function(scope, element)`: Callback function used to announce the show() action is
 *     starting.
 *   - `onComplete` - `function(scope, element)`: Callback function used to announce when the show() action is
 *     finished.
 *   - `onRemoving` - `function(element, removePromise)`: Callback function used to announce the
 *      close/hide() action is starting. This allows developers to run custom animations
 *      in parallel the close animations.
 *   - `fullscreen` `{boolean=}`: An option to toggle whether the dialog should show in fullscreen
 *      or not. Defaults to `false`.
 * @returns {promise} A promise that can be resolved with `$mdDialog.hide()` or
 * rejected with `$mdDialog.cancel()`.

   *
   * @description
   * The `<md-fab-speed-dial>` directive is used to present a series of popup elements (usually
   * `<md-button>`s) for quick access to common actions.
   *
   * There are currently two animations available by applying one of the following classes to
   * the component:
   *
   *  - `md-fling` - The speed dial items appear from underneath the trigger and move into their
   *    appropriate positions.
   *  - `md-scale` - The speed dial items appear in their proper places by scaling from 0% to 100%.
   *
   * You may also easily position the trigger by applying one one of the following classes to the
   * `<md-fab-speed-dial>` element:
   *  - `md-fab-top-left`
   *  - `md-fab-top-right`
   *  - `md-fab-bottom-left`
   *  - `md-fab-bottom-right`
   *
   * These CSS classes use `position: absolute`, so you need to ensure that the container element
   * also uses `position: absolute` or `position: relative` in order for them to work.
   *
   * Additionally, you may use the standard `ng-mouseenter` and `ng-mouseleave` directives to
   * open or close the speed dial. However, if you wish to allow users to hover over the empty
   * space where the actions will appear, you must also add the `md-hover-full` class to the speed
   * dial element. Without this, the hover effect will only occur on top of the trigger.
   *
   * See the demos for more information.
   *
   * ## Troubleshooting
   *
   * If your speed dial shows the closing animation upon launch, you may need to use `ng-cloak` on
   * the parent container to ensure that it is only visible once ready. We have plans to remove this
   * necessity in the future.

   * The `<md-fab-toolbar>` directive is used present a toolbar of elements (usually `<md-button>`s)
   * for quick access to common actions when a floating action button is activated (via click or
   * keyboard navigation).
   *
   * You may also easily position the trigger by applying one one of the following classes to the
   * `<md-fab-toolbar>` element:
   *  - `md-fab-top-left`
   *  - `md-fab-top-right`
   *  - `md-fab-bottom-left`
   *  - `md-fab-bottom-right`
   *
   * These CSS classes use `position: absolute`, so you need to ensure that the container element
   * also uses `position: absolute` or `position: relative` in order for them to work.

 * @description
 * Grid lists are an alternative to standard list views. Grid lists are distinct
 * from grids used for layouts and other visual presentations.
 *
 * A grid list is best suited to presenting a homogenous data type, typically
 * images, and is optimized for visual comprehension and differentiating between
 * like data types.
 *
 * A grid list is a continuous element consisting of tessellated, regular
 * subdivisions called cells that contain tiles (`md-grid-tile`).

 *
 * Cells are arrayed vertically and horizontally within the grid.
 *
 * Tiles hold content and can span one or more cells vertically or horizontally.
 *
 * ### Responsive Attributes
 *
 * The `md-grid-list` directive supports "responsive" attributes, which allow
 * different `md-cols`, `md-gutter` and `md-row-height` values depending on the
 * currently matching media query.
 *
 * In order to set a responsive attribute, first define the fallback value with
 * the standard attribute name, then add additional attributes with the
 * following convention: `{base-attribute-name}-{media-query-name}="{value}"`
 * (ie. `md-cols-lg="8"`)
 *
 * @param {number} md-cols Number of columns in the grid.
 * @param {string} md-row-height One of
 * <ul>
 *   <li>CSS length - Fixed height rows (eg. `8px` or `1rem`)</li>
 *   <li>`{width}:{height}` - Ratio of width to height (eg.
 *   `md-row-height="16:9"`)</li>
 *   <li>`"fit"` - Height will be determined by subdividing the available
 *   height by the number of rows</li>
 * </ul>
 * @param {string=} md-gutter The amount of space between tiles in CSS units
 *     (default 1px)
 * @param {expression=} md-on-layout Expression to evaluate after layout. Event
 *     object is available as `$event`, and contains performance information.
 *
 * @usage
 * Basic:
 * <hljs lang="html">
 * <md-grid-list md-cols="5" md-gutter="1em" md-row-height="4:3">
 *   <md-grid-tile></md-grid-tile>
 * </md-grid-list>
 * </hljs>
 *
 * Fixed-height rows:
 * <hljs lang="html">
 * <md-grid-list md-cols="4" md-row-height="200px" ...>
 *   <md-grid-tile></md-grid-tile>
 * </md-grid-list>
 * </hljs>
 *
 * Fit rows:
 * <hljs lang="html">
 * <md-grid-list md-cols="4" md-row-height="fit" style="height: 400px;" ...>

/**
 * @ngdoc directive
 * @name mdInput
 * @restrict E
 * @module material.components.input
 *
 * @description
 * You can use any `<input>` or `<textarea>` element as a child of an `<md-input-container>`. This
 * allows you to build complex forms for data entry.
 *
 * When the input is required and uses a floating label, then the label will automatically contain
 * an asterisk (`*`).<br/>
 * This behavior can be disabled by using the `md-no-asterisk` attribute.
 *
 * @param {number=} md-maxlength The maximum number of characters allowed in this input. If this is
 *   specified, a character counter will be shown underneath the input.<br/><br/>
 *   The purpose of **`md-maxlength`** is exactly to show the max length counter text. If you don't
 *   want the counter text and only need "plain" validation, you can use the "simple" `ng-maxlength`
 *   or maxlength attributes.<br/><br/>
 *   **Note:** Only valid for text/string inputs (not numeric).
 *
 * @param {string=} aria-label Aria-label is required when no label is present.  A warning message
 *   will be logged in the console if not present.
 * @param {string=} placeholder An alternative approach to using aria-label when the label is not
 *   PRESENT. The placeholder text is copied to the aria-label attribute.
 * @param md-no-autogrow {boolean=} When present, textareas will not grow automatically.
 * @param md-no-asterisk {boolean=} When present, an asterisk will not be appended to the inputs floating label
 * @param md-no-resize {boolean=} Disables the textarea resize handle.
 * @param {number=} max-rows The maximum amount of rows for a textarea.
 * @param md-detect-hidden {boolean=} When present, textareas will be sized properly when they are
 *   revealed after being hidden. This is off by default for performance reasons because it
 *   guarantees a reflow every digest cycle.
 *

 *
 * <h3>With Errors</h3>
 *
 * `md-input-container` also supports errors using the standard `ng-messages` directives and
 * animates the messages when they become visible using from the `ngEnter`/`ngLeave` events or
 * the `ngShow`/`ngHide` events.
 *
 * By default, the messages will be hidden until the input is in an error state. This is based off
 * of the `md-is-error` expression of the `md-input-container`. This gives the user a chance to
 * fill out the form before the errors become visible.
 *
 * <hljs lang="html">
 * <form name="colorForm">
 *   <md-input-container>
 *     <label>Favorite Color</label>
 *     <input name="favoriteColor" ng-model="favoriteColor" required>
 *     <div ng-messages="colorForm.favoriteColor.$error">
 *       <div ng-message="required">This is required!</div>
 *     </div>
 *   </md-input-container>
 * </form>
 * </hljs>
 *
 * We automatically disable this auto-hiding functionality if you provide any of the following
 * visibility directives on the `ng-messages` container:
 *
 *  - `ng-if`
 *  - `ng-show`/`ng-hide`
 *  - `ng-switch-when`/`ng-switch-default`
 *
 * You can also disable this functionality manually by adding the `md-auto-hide="false"` expression
 * to the `ng-messages` container. This may be helpful if you always want to see the error messages
 * or if you are building your own visibilty directive.
 *
 * _<b>Note:</b> The `md-auto-hide` attribute is a static string that is  only checked upon
 * initialization of the `ng-messages` directive to see if it equals the string `false`._

 *
 * <h3>Notes</h3>
 *
 * - Requires [ngMessages](https://docs.angularjs.org/api/ngMessages).
 * - Behaves like the [AngularJS input directive](https://docs.angularjs.org/api/ng/directive/input).
 *
 * The `md-input` and `md-input-container` directives use very specific positioning to achieve the
 * error animation effects. Therefore, it is *not* advised to use the Layout system inside of the
 * `<md-input-container>` tags. Instead, use relative or absolute positioning.
 *
 *
 * <h3>Textarea directive</h3>
 * The `textarea` element within a `md-input-container` has the following specific behavior:
 * - By default the `textarea` grows as the user types. This can be disabled via the `md-no-autogrow`
 * attribute.
 * - If a `textarea` has the `rows` attribute, it will treat the `rows` as the minimum height and will
 * continue growing as the user types. For example a textarea with `rows="3"` will be 3 lines of text
 * high initially. If no rows are specified, the directive defaults to 1.
 * - The textarea's height gets set on initialization, as well as while the user is typing. In certain situations
 * (e.g. while animating) the directive might have been initialized, before the element got it's final height. In
 * those cases, you can trigger a resize manually by broadcasting a `md-resize-textarea` event on the scope.
 * - If you wan't a `textarea` to stop growing at a certain point, you can specify the `max-rows` attribute.
 * - The textarea's bottom border acts as a handle which users can drag, in order to resize the element vertically.
 * Once the user has resized a `textarea`, the autogrowing functionality becomes disabled. If you don't want a
 * `textarea` to be resizeable by the user, you can add the `md-no-resize` attribute.

 *
 * @usage
 * ### Single Row Item
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>Single Row Item</span>
 *   </md-list-item>
 * </hljs>
 *
 * ### Multiple Lines
 * By using the following markup, you will be able to have two lines inside of one `md-list-item`.
 *
 * <hljs lang="html">
 *   <md-list-item class="md-2-line">
 *     <div class="md-list-item-text" layout="column">
 *       <p>First Line</p>
 *       <p>Second Line</p>
 *     </div>
 *   </md-list-item>
 * </hljs>
 *
 * It is also possible to have three lines inside of one list item.
 *
 * <hljs lang="html">
 *   <md-list-item class="md-3-line">
 *     <div class="md-list-item-text" layout="column">
 *       <p>First Line</p>
 *       <p>Second Line</p>
 *       <p>Third Line</p>
 *     </div>
 *   </md-list-item>
 * </hljs>
 *
 * ### Secondary Items
 * Secondary items are elements which will be aligned at the end of the `md-list-item`.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>Single Row Item</span>
 *     <md-button class="md-secondary">
 *       Secondary Button
 *     </md-button>
 *   </md-list-item>
 * </hljs>
 *
 * It also possible to have multiple secondary items inside of one `md-list-item`.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>Single Row Item</span>
 *     <md-button class="md-secondary">First Button</md-button>
 *     <md-button class="md-secondary">Second Button</md-button>
 *   </md-list-item>
 * </hljs>
 *
 * ### Proxy Item
 * Proxies are elements, which will execute their specific action on click<br/>
 * Currently supported proxy items are
 * - `md-checkbox` (Toggle)
 * - `md-switch` (Toggle)
 * - `md-menu` (Open)
 *
 * This means, when using a supported proxy item inside of `md-list-item`, the list item will
 * become clickable and executes the associated action of the proxy element on click.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>First Line</span>
 *     <md-checkbox class="md-secondary"></md-checkbox>
 *   </md-list-item>
 * </hljs>
 *
 * The `md-checkbox` element will be automatically detected as a proxy element and will toggle on click.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>First Line</span>
 *     <md-switch class="md-secondary"></md-switch>
 *   </md-list-item>
 * </hljs>
 *
 * The recognized `md-switch` will toggle its state, when the user clicks on the `md-list-item`.
 *
 * It is also possible to have a `md-menu` inside of a `md-list-item`.
 * <hljs lang="html">
 *   <md-list-item>
 *     <p>Click anywhere to fire the secondary action</p>
 *     <md-menu class="md-secondary">
 *       <md-button class="md-icon-button">
 *         <md-icon md-svg-icon="communication:message"></md-icon>
 *       </md-button>
 *       <md-menu-content width="4">
 *         <md-menu-item>
 *           <md-button>
 *             Redial
 *           </md-button>
 *         </md-menu-item>
 *         <md-menu-item>
 *           <md-button>
 *             Check voicemail
 *           </md-button>
 *         </md-menu-item>
 *         <md-menu-divider></md-menu-divider>
 *         <md-menu-item>
 *           <md-button>
 *             Notifications
 *           </md-button>
 *         </md-menu-item>
 *       </md-menu-content>
 *     </md-menu>
 *   </md-list-item>
 * </hljs>
 *
 * The menu will automatically open, when the users clicks on the `md-list-item`.<br/>
 *
 * If the developer didn't specify any position mode on the menu, the `md-list-item` will automatically detect the
 * position mode and applies it to the `md-menu`.
 *
 * ### Avatars
 * Sometimes you may want to have some avatars inside of the `md-list-item `.<br/>
 * You are able to create a optimized icon for the list item, by applying the `.md-avatar` class on the `<img>` element.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <img src="my-avatar.png" class="md-avatar">
 *     <span>Alan Turing</span>
 * </hljs>
 *
 * When using `<md-icon>` for an avater, you have to use the `.md-avatar-icon` class.
 * <hljs lang="html">
 *   <md-list-item>
 *     <md-icon class="md-avatar-icon" md-svg-icon="avatars:timothy"></md-icon>
 *     <span>Timothy Kopra</span>
 *   </md-list-item>
 * </hljs>
 *
 * In cases, you have a `md-list-item`, which doesn't have any avatar,
 * but you want to align it with the other avatar items, you have to use the `.md-offset` class.
 *
 * <hljs lang="html">
 *   <md-list-item class="md-offset">
 *     <span>Jon Doe</span>
 *   </md-list-item>
 * </hljs>
 *
 * ### DOM modification
 * The `md-list-item` component automatically detects if the list item should be clickable.
 *
 * ---
 * If the `md-list-item` is clickable, we wrap all content inside of a `<div>` and create
 * an overlaying button, which will will execute the given actions (like `ng-href`, `ng-click`)
 *
 * We create an overlaying button, instead of wrapping all content inside of the button,
 * because otherwise some elements may not be clickable inside of the button.
 *
 * ---
 * When using a secondary item inside of your list item, the `md-list-item` component will automatically create
 * a secondary container at the end of the `md-list-item`, which contains all secondary items.
 *
 * The secondary item container is not static, because otherwise the overflow will not work properly on the
 * list item.

/**
 * @ngdoc method
 * @name $mdPanel#create
 * @description
 * Creates a panel with the specified options.
 *
 * @param config {!Object=} Specific configuration object that may contain the
 *     following properties:
 *
 *   - `id` - `{string=}`: An ID to track the panel by. When an ID is provided,
 *     the created panel is added to a tracked panels object. Any subsequent
 *     requests made to create a panel with that ID are ignored. This is useful
 *     in having the panel service not open multiple panels from the same user
 *     interaction when there is no backdrop and events are propagated. Defaults
 *     to an arbitrary string that is not tracked.
 *   - `template` - `{string=}`: HTML template to show in the panel. This
 *     **must** be trusted HTML with respect to Angular’s
 *     [$sce service](https://docs.angularjs.org/api/ng/service/$sce).
 *   - `templateUrl` - `{string=}`: The URL that will be used as the content of
 *     the panel.
 *   - `controller` - `{(function|string)=}`: The controller to associate with
 *     the panel. The controller can inject a reference to the returned
 *     panelRef, which allows the panel to be closed, hidden, and shown. Any
 *     fields passed in through locals or resolve will be bound to the
 *     controller.
 *   - `controllerAs` - `{string=}`: An alias to assign the controller to on
 *     the scope.
 *   - `bindToController` - `{boolean=}`: Binds locals to the controller
 *     instead of passing them in. Defaults to true, as this is a best
 *     practice.
 *   - `locals` - `{Object=}`: An object containing key/value pairs. The keys
 *     will be used as names of values to inject into the controller. For
 *     example, `locals: {three: 3}` would inject `three` into the controller,
 *     with the value 3.
 *   - `resolve` - `{Object=}`: Similar to locals, except it takes promises as
 *     values. The panel will not open until all of the promises resolve.
 *   - `attachTo` - `{(string|!angular.JQLite|!Element)=}`: The element to
 *     attach the panel to. Defaults to appending to the root element of the
 *     application.
 *   - `propagateContainerEvents` - `{boolean=}`: Whether pointer or touch
 *     events should be allowed to propagate 'go through' the container, aka the
 *     wrapper, of the panel. Defaults to false.
 *   - `panelClass` - `{string=}`: A css class to apply to the panel element.
 *     This class should define any borders, box-shadow, etc. for the panel.
 *   - `zIndex` - `{number=}`: The z-index to place the panel at.
 *     Defaults to 80.
 *   - `position` - `{MdPanelPosition=}`: An MdPanelPosition object that
 *     specifies the alignment of the panel. For more information, see
 *     `MdPanelPosition`.
 *   - `clickOutsideToClose` - `{boolean=}`: Whether the user can click
 *     outside the panel to close it. Defaults to false.
 *   - `escapeToClose` - `{boolean=}`: Whether the user can press escape to
 *     close the panel. Defaults to false.
 *   - `trapFocus` - `{boolean=}`: Whether focus should be trapped within the
 *     panel. If `trapFocus` is true, the user will not be able to interact
 *     with the rest of the page until the panel is dismissed. Defaults to
 *     false.
 *   - `focusOnOpen` - `{boolean=}`: An option to override focus behavior on
 *     open. Only disable if focusing some other way, as focus management is
 *     required for panels to be accessible. Defaults to true.
 *   - `fullscreen` - `{boolean=}`: Whether the panel should be full screen.
 *     Applies the class `._md-panel-fullscreen` to the panel on open. Defaults
 *     to false.
 *   - `animation` - `{MdPanelAnimation=}`: An MdPanelAnimation object that
 *     specifies the animation of the panel. For more information, see
 *     `MdPanelAnimation`.
 *   - `hasBackdrop` - `{boolean=}`: Whether there should be an opaque backdrop
 *     behind the panel. Defaults to false.
 *   - `disableParentScroll` - `{boolean=}`: Whether the user can scroll the
 *     page behind the panel. Defaults to false.
 *   - `onDomAdded` - `{function=}`: Callback function used to announce when
 *     the panel is added to the DOM.
 *   - `onOpenComplete` - `{function=}`: Callback function used to announce
 *     when the open() action is finished.
 *   - `onRemoving` - `{function=}`: Callback function used to announce the
 *     close/hide() action is starting.
 *   - `onDomRemoved` - `{function=}`: Callback function used to announce when
 *     the panel is removed from the DOM.
 *   - `origin` - `{(string|!angular.JQLite|!Element)=}`: The element to focus
 *     on when the panel closes. This is commonly the element which triggered
 *     the opening of the panel. If you do not use `origin`, you need to control
 *     the focus manually.

 * the amount of visual change a user sees before they can view
 * and interact with content.
 *
 * Each operation should only be represented by one activity indicator
 * For example: one refresh operation should not display both a
 * refresh bar and an activity circle.
 *
 * For operations where the percentage of the operation completed
 * can be determined, use a determinate indicator. They give users
 * a quick sense of how long an operation will take.
 *
 * For operations where the user is asked to wait a moment while
 * something finishes up, and it’s not necessary to expose what's
 * happening behind the scenes and how long it will take, use an
 * indeterminate indicator.
 *
 * @param {string} md-mode Select from one of four modes: determinate, indeterminate, buffer or query.
 *
 * Note: if the `md-mode` value is set as undefined or specified as 1 of the four (4) valid modes, then `indeterminate`
 * will be auto-applied as the mode.
 *
 * Note: if not configured, the `md-mode="indeterminate"` will be auto injected as an attribute. If `value=""` is also specified, however,
 * then `md-mode="determinate"` would be auto-injected instead.
 * @param {number=} value In determinate and buffer modes, this number represents the percentage of the primary progress bar. Default: 0
 * @param {number=} md-buffer-value In the buffer mode, this number represents the percentage of the secondary progress bar. Default: 0

/**
 * @ngdoc directive
 * @name mdSelect
 * @restrict E
 * @module material.components.select
 *
 * @description Displays a select box, bound to an ng-model.
 *
 * When the select is required and uses a floating label, then the label will automatically contain
 * an asterisk (`*`). This behavior can be disabled by using the `md-no-asterisk` attribute.
 *
 * By default, the select will display with an underline to match other form elements. This can be
 * disabled by applying the `md-no-underline` CSS class.
 *
 * ### Option Params
 *
 * When applied, `md-option-empty` will mark the option as "empty" allowing the option to  clear the
 * select and put it back in it's default state. You may supply this attribute on any option you
 * wish, however, it is automatically applied to an option whose `value` or `ng-value` are not
 * defined.
 *
 * **Automatically Applied**
 *
 *  - `<md-option>`
 *  - `<md-option value>`
 *  - `<md-option value="">`
 *  - `<md-option ng-value>`
 *  - `<md-option ng-value="">`
 *
 * **NOT Automatically Applied**
 *
 *  - `<md-option ng-value="1">`
 *  - `<md-option ng-value="''">`
 *  - `<md-option ng-value="undefined">`
 *  - `<md-option value="undefined">` (this evaluates to the string `"undefined"`)
 *  - <code ng-non-bindable>&lt;md-option ng-value="{{someValueThatMightBeUndefined}}"&gt;</code>
 *
 * **Note:** A value of `undefined` ***is considered a valid value*** (and does not auto-apply this
 * attribute) since you may wish this to be your "Not Available" or "None" option.
 *
 * **Note:** Using the `value` attribute (as opposed to `ng-value`) always evaluates to a string, so
 * `value="null"` will require the test `ng-if="myValue != 'null'"` rather than `ng-if="!myValue"`.
 *
 * @param {expression} ng-model The model!
 * @param {boolean=} multiple Whether it's multiple.
 * @param {expression=} md-on-close Expression to be evaluated when the select is closed.
 * @param {expression=} md-on-open Expression to be evaluated when opening the select.
 * Will hide the select options and show a spinner until the evaluated promise resolves.
 * @param {expression=} md-selected-text Expression to be evaluated that will return a string
 * to be displayed as a placeholder in the select input box when it is closed.
 * @param {string=} placeholder Placeholder hint text.
 * @param md-no-asterisk {boolean=} When set to true, an asterisk will not be appended to the
 * floating label. **Note:** This attribute is only evaluated once; it is not watched.
 * @param {string=} aria-label Optional label for accessibility. Only necessary if no placeholder or
 * explicit label is present.
 * @param {string=} md-container-class Class list to get applied to the `.md-select-menu-container`
 * element (for custom styling).
 *
 * @usage
 * With a placeholder (label and aria-label are added dynamically)
 * <hljs lang="html">
 *   <md-input-container>
 *     <md-select
 *       ng-model="someModel"
 *       placeholder="Select a state">
 *       <md-option ng-value="opt" ng-repeat="opt in neighborhoods2">{{ opt }}</md-option>
 *     </md-select>
 *   </md-input-container>
 * </hljs>
 *
 * With an explicit label
 * <hljs lang="html">
 *   <md-input-container>
 *     <label>State</label>
 *     <md-select
 *       ng-model="someModel">
 *       <md-option ng-value="opt" ng-repeat="opt in neighborhoods2">{{ opt }}</md-option>
 *     </md-select>
 *   </md-input-container>
 * </hljs>
 *
 * With a select-header
 *
 * When a developer needs to put more than just a text label in the
 * md-select-menu, they should use the md-select-header.
 * The user can put custom HTML inside of the header and style it to their liking.
 * One common use case of this would be a sticky search bar.
 *
 * When using the md-select-header the labels that would previously be added to the
 * OptGroupDirective are ignored.
 *
 * <hljs lang="html">
 *   <md-input-container>
 *     <md-select ng-model="someModel">
 *       <md-select-header>
 *         <span> Neighborhoods - </span>
 *       </md-select-header>
 *       <md-option ng-value="opt" ng-repeat="opt in neighborhoods2">{{ opt }}</md-option>
 *     </md-select>
 *   </md-input-container>
 * </hljs>
 *
 * ## Selects and object equality
 * When using a `md-select` to pick from a list of objects, it is important to realize how javascript handles
 * equality. Consider the following example:
 * <hljs lang="js">
 * angular.controller('MyCtrl', function($scope) {
 *   $scope.users = [
 *     { id: 1, name: 'Bob' },
 *     { id: 2, name: 'Alice' },
 *     { id: 3, name: 'Steve' }
 *   ];
 *   $scope.selectedUser = { id: 1, name: 'Bob' };
 * });
 * </hljs>
 * <hljs lang="html">
 * <div ng-controller="MyCtrl">
 *   <md-select ng-model="selectedUser">
 *     <md-option ng-value="user" ng-repeat="user in users">{{ user.name }}</md-option>
 *   </md-select>
 * </div>
 * </hljs>
 *
 * At first one might expect that the select should be populated with "Bob" as the selected user. However,
 * this is not true. To determine whether something is selected,
 * `ngModelController` is looking at whether `$scope.selectedUser == (any user in $scope.users);`;
 *
 * Javascript's `==` operator does not check for deep equality (ie. that all properties
 * on the object are the same), but instead whether the objects are *the same object in memory*.
 * In this case, we have two instances of identical objects, but they exist in memory as unique
 * entities. Because of this, the select will have no value populated for a selected user.
 *
 * To get around this, `ngModelController` provides a `track by` option that allows us to specify a different
 * expression which will be used for the equality operator. As such, we can update our `html` to
 * make use of this by specifying the `ng-model-options="{trackBy: '$value.id'}"` on the `md-select`
 * element. This converts our equality expression to be
 * `$scope.selectedUser.id == (any id in $scope.users.map(function(u) { return u.id; }));`
 * which results in Bob being selected as desired.
 *
 * Working HTML:
 * <hljs lang="html">
 * <div ng-controller="MyCtrl">
 *   <md-select ng-model="selectedUser" ng-model-options="{trackBy: '$value.id'}">
 *     <md-option ng-value="user" ng-repeat="user in users">{{ user.name }}</md-option>
 *   </md-select>
 * </div>
 * </hljs>

/**
 * @ngdoc directive
 * @name mdSlider
 * @module material.components.slider
 * @restrict E
 * @description
 * The `<md-slider>` component allows the user to choose from a range of
 * values.
 *
 * As per the [material design spec](http://www.google.com/design/spec/style/color.html#color-ui-color-application)
 * the slider is in the accent color by default. The primary color palette may be used with
 * the `md-primary` class.
 *
 * It has two modes: 'normal' mode, where the user slides between a wide range
 * of values, and 'discrete' mode, where the user slides between only a few
 * select values.
 *
 * To enable discrete mode, add the `md-discrete` attribute to a slider,
 * and use the `step` attribute to change the distance between
 * values the user is allowed to pick.
 *
 * @usage
 * <h4>Normal Mode</h4>
 * <hljs lang="html">
 * <md-slider ng-model="myValue" min="5" max="500">
 * </md-slider>
 * </hljs>
 * <h4>Discrete Mode</h4>
 * <hljs lang="html">
 * <md-slider md-discrete ng-model="myDiscreteValue" step="10" min="10" max="130">
 * </md-slider>
 * </hljs>
 * <h4>Invert Mode</h4>
 * <hljs lang="html">
 * <md-slider md-invert ng-model="myValue" step="10" min="10" max="130">
 * </md-slider>
 * </hljs>
 *
 * @param {boolean=} md-discrete Whether to enable discrete mode.
 * @param {boolean=} md-invert Whether to enable invert mode.
 * @param {number=} step The distance between values the user is allowed to pick. Default 1.
 * @param {number=} min The minimum value the user is allowed to pick. Default 0.
 * @param {number=} max The maximum value the user is allowed to pick. Default 100.
 * @param {number=} round The amount of numbers after the decimal point, maximum is 6 to prevent scientific notation. Default 3.

/**
  * @ngdoc service
  * @name $mdToast
  * @module material.components.toast
  *
  * @description
  * `$mdToast` is a service to build a toast notification on any position
  * on the screen with an optional duration, and provides a simple promise API.
  *
  * The toast will be always positioned at the `bottom`, when the screen size is
  * between `600px` and `959px` (`sm` breakpoint)
  *
  * ## Restrictions on custom toasts
  * - The toast's template must have an outer `<md-toast>` element.
  * - For a toast action, use element with class `md-action`.
  * - Add the class `md-capsule` for curved corners.
  *
  * ### Custom Presets
  * Developers are also able to create their own preset, which can be easily used without repeating
  * their options each time.
  *
  * <hljs lang="js">
  *   $mdToastProvider.addPreset('testPreset', {
  *     options: function() {
  *       return {
  *         template:
  *           '<md-toast>' +
  *             '<div class="md-toast-content">' +
  *               'This is a custom preset' +
  *             '</div>' +
  *           '</md-toast>',
  *         controllerAs: 'toast',
  *         bindToController: true
  *       };
  *     }
  *   });
  * </hljs>
  *
  * After you created your preset at config phase, you can easily access it.
  *
  * <hljs lang="js">
  *   $mdToast.show(
  *     $mdToast.testPreset()
  *   );
  * </hljs>
  *
  * ## Parent container notes
  *
  * The toast is positioned using absolute positioning relative to its first non-static parent
  * container. Thus, if the requested parent container uses static positioning, we will temporarily
  * set its positioning to `relative` while the toast is visible and reset it when the toast is
  * hidden.
  *
  * Because of this, it is usually best to ensure that the parent container has a fixed height and
  * prevents scrolling by setting the `overflow: hidden;` style. Since the position is based off of
  * the parent's height, the toast may be mispositioned if you allow the parent to scroll.
  *
  * You can, however, have a scrollable element inside of the container; just make sure the
  * container itself does not scroll.
  *
  * <hljs lang="html">
  * <div layout-fill id="toast-container">
  *   <md-content>
  *     I can have lots of content and scroll!
  *   </md-content>
  * </div>
  * </hljs>
  *
  * @usage
  * <hljs lang="html">
  * <div ng-controller="MyController">
  *   <md-button ng-click="openToast()">
  *     Open a Toast!
  *   </md-button>

  *

  *
  *   - `templateUrl` - `{string=}`: The url of an html template file that will
  *     be used as the content of the toast. Restrictions: the template must
  *     have an outer `md-toast` element.
  *   - `template` - `{string=}`: Same as templateUrl, except this is an actual
  *     template string.
  *   - `autoWrap` - `{boolean=}`: Whether or not to automatically wrap the template content with a
  *     `<div class="md-toast-content">` if one is not provided. Defaults to true. Can be disabled if you provide a
  *     custom toast directive.
  *   - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified, it will create a new child scope.
  *     This scope will be destroyed when the toast is removed unless `preserveScope` is set to true.
  *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
  *   - `hideDelay` - `{number=}`: How many milliseconds the toast should stay
  *     active before automatically closing.  Set to 0 or false to have the toast stay open until
  *     closed manually. Default: 3000.
  *   - `position` - `{string=}`: Sets the position of the toast. <br/>
  *     Available: any combination of `'bottom'`, `'left'`, `'top'`, `'right'`, `'end'` and `'start'`.
  *     The properties `'end'` and `'start'` are dynamic and can be used for RTL support.<br/>
  *     Default combination: `'bottom left'`.
  *   - `toastClass` - `{string=}`: A class to set on the toast element.
  *   - `controller` - `{string=}`: The controller to associate with this toast.
  *     The controller will be injected the local `$mdToast.hide( )`, which is a function
  *     used to hide the toast.
  *   - `locals` - `{string=}`: An object containing key/value pairs. The keys will
  *     be used as names of values to inject into the controller. For example,
  *     `locals: {three: 3}` would inject `three` into the controller with the value
  *     of 3.
  *   - `bindToController` - `bool`: bind the locals to the controller, instead of passing them in.
  *   - `resolve` - `{object=}`: Similar to locals, except it takes promises as values
  *     and the toast will not open until the promises resolve.
  *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
  *   - `parent` - `{element=}`: The element to append the toast to. Defaults to appending
  *     to the root element of the application.
  *
  * @returns {promise} A promise that can be resolved with `$mdToast.hide()` or
  * rejected with `$mdToast.cancel()`. `$mdToast.hide()` will resolve either with a Boolean
  * value == 'true' or the value passed as an argument to `$mdToast.hide()`.

/**
 * @ngdoc directive
 * @name mdVirtualRepeatContainer
 * @module material.components.virtualRepeat
 * @restrict E
 * @description
 * `md-virtual-repeat-container` provides the scroll container for md-virtual-repeat.
 *
 * VirtualRepeat is a limited substitute for ng-repeat that renders only
 * enough DOM nodes to fill the container and recycling them as the user scrolls.
 *
 * Once an element is not visible anymore, the VirtualRepeat recycles it and will reuse it for
 * another visible item by replacing the previous dataset with the new one.
 *
 * ### Common Issues
 *
 * > When having one-time bindings inside of the view template, the VirtualRepeat will not properly
 * > update the bindings for new items, since the view will be recycled.
 *
 * ### Notes
 *
 * > The VirtualRepeat is a similar implementation to the Android
 * [RecyclerView](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.html)
 *
 * <!-- This comment forces a break between blockquotes //-->

 * documentation for more information.

 *
 * @param {number=} md-top-index Binds the index of the item that is at the top of the scroll
 *     container to $scope. It can both read and set the scroll position.

 * @ngdoc directive

 * @module material.components.virtualRepeat
 * @restrict A
 * @priority 1000
 * @description
 * `md-virtual-repeat` specifies an element to repeat using virtual scrolling.
 *
 * Virtual repeat is a limited substitute for ng-repeat that renders only
 * enough dom nodes to fill the container and recycling them as the user scrolls.
 * Arrays, but not objects are supported for iteration.
 * Track by, as alias, and (key, value) syntax are not supported.
 *
 * > <b>Note:</b> Please also review the
 *   <a ng-href="api/directive/mdVirtualRepeatContainer">VirtualRepeatContainer</a> documentation
 *   for more information.
 *
 * @usage
 * <hljs lang="html">
 * <md-virtual-repeat-container>
 *   <div md-virtual-repeat="i in items">Hello {{i}}!</div>
 * </md-virtual-repeat-container>
 *
 * <md-virtual-repeat-container md-orient-horizontal>
 *   <div md-virtual-repeat="i in items" md-item-size="20">Hello {{i}}!</div>
 * </md-virtual-repeat-container>
 * </hljs>
 *
 * @param {number=} md-item-size The height or width of the repeated elements (which must be
 *   identical for each element). Optional. Will attempt to read the size from the dom if missing,
 *   but still assumes that all repeated nodes have same height or width.
 * @param {string=} md-extra-name Evaluates to an additional name to which the current iterated item
 *   can be assigned on the repeated scope (needed for use in `md-autocomplete`).
 * @param {boolean=} md-on-demand When present, treats the md-virtual-repeat argument as an object
 *   that can fetch rows rather than an array.
 *
 *   **NOTE:** This object must implement the following interface with two (2) methods:
 *
 *   - `getItemAtIndex: function(index) [object]` The item at that index or null if it is not yet
 *     loaded (it should start downloading the item in that case).
 *   - `getLength: function() [number]` The data length to which the repeater container
 *     should be sized. Ideally, when the count is known, this method should return it.
 *     Otherwise, return a higher number than the currently loaded items to produce an
 *     infinite-scroll behavior.

    .directive('mdAutocomplete', MdAutocomplete);

/**
 * @ngdoc directive
 * @name mdAutocomplete
 * @module material.components.autocomplete
 *
 * @description
 * `<md-autocomplete>` is a special input component with a drop-down of all possible matches to a
 *     custom query. This component allows you to provide real-time suggestions as the user types
 *     in the input area.
 *
 * To start, you will need to specify the required parameters and provide a template for your
 *     results. The content inside `md-autocomplete` will be treated as a template.
 *
 * In more complex cases, you may want to include other content such as a message to display when
 *     no matches were found.  You can do this by wrapping your template in `md-item-template` and
 *     adding a tag for `md-not-found`.  An example of this is shown below.
 *
 * To reset the displayed value you must clear both values for `md-search-text` and `md-selected-item`.
 *
 * ### Validation
 *
 * You can use `ng-messages` to include validation the same way that you would normally validate;
 *     however, if you want to replicate a standard input with a floating label, you will have to
 *     do the following:
 *
 * - Make sure that your template is wrapped in `md-item-template`
 * - Add your `ng-messages` code inside of `md-autocomplete`
 * - Add your validation properties to `md-autocomplete` (ie. `required`)
 * - Add a `name` to `md-autocomplete` (to be used on the generated `input`)
 *
 * There is an example below of how this should look.
 *
 * ### Notes
 * The `md-autocomplete` uses the the <a ng-href="api/directive/mdVirtualRepeatContainer">VirtualRepeat</a>
 * directive for displaying the results inside of the dropdown.<br/>
 * > When encountering issues regarding the item template please take a look at the
 *   <a ng-href="api/directive/mdVirtualRepeatContainer">VirtualRepeatContainer</a> documentation.
 *
 *
 * @param {expression} md-items An expression in the format of `item in items` to iterate over
 *     matches for your search.
 * @param {expression=} md-selected-item-change An expression to be run each time a new item is
 *     selected
 * @param {expression=} md-search-text-change An expression to be run each time the search text
 *     updates
 * @param {expression=} md-search-text A model to bind the search query text to
 * @param {object=} md-selected-item A model to bind the selected item to
 * @param {expression=} md-item-text An expression that will convert your object to a single string.
 * @param {string=} placeholder Placeholder text that will be forwarded to the input.
 * @param {boolean=} md-no-cache Disables the internal caching that happens in autocomplete
 * @param {boolean=} ng-disabled Determines whether or not to disable the input field
 * @param {boolean=} md-require-match When set to true, the autocomplete will add a validator,
 *     which will evaluate to false, when no item is currently selected.
 * @param {number=} md-min-length Specifies the minimum length of text before autocomplete will
 *     make suggestions
 * @param {number=} md-delay Specifies the amount of time (in milliseconds) to wait before looking
 *     for results
 * @param {boolean=} md-autofocus If true, the autocomplete will be automatically focused when a `$mdDialog`,
 *     `$mdBottomsheet` or `$mdSidenav`, which contains the autocomplete, is opening. <br/><br/>
 *     Also the autocomplete will immediately focus the input element.
 * @param {boolean=} md-no-asterisk When present, asterisk will not be appended to the floating label
 * @param {boolean=} md-autoselect If set to true, the first item will be automatically selected
 *     in the dropdown upon open.
 * @param {string=} md-menu-class This will be applied to the dropdown menu for styling
 * @param {string=} md-floating-label This will add a floating label to autocomplete and wrap it in
 *     `md-input-container`
 * @param {string=} md-input-name The name attribute given to the input element to be used with
 *     FormController
 * @param {string=} md-select-on-focus When present the inputs text will be automatically selected
 *     on focus.
 * @param {string=} md-input-id An ID to be added to the input element
 * @param {number=} md-input-minlength The minimum length for the input's value for validation
 * @param {number=} md-input-maxlength The maximum length for the input's value for validation
 * @param {boolean=} md-select-on-match When set, autocomplete will automatically select exact
 *     the item if the search text is an exact match. <br/><br/>
 *     Exact match means that there is only one match showing up.
 * @param {boolean=} md-match-case-insensitive When set and using `md-select-on-match`, autocomplete
 *     will select on case-insensitive match
 * @param {string=} md-escape-options Override escape key logic. Default is `blur clear`.<br/>
 *     Options: `blur | clear`, `none`
 *
 * @usage
 * ### Basic Example
 * <hljs lang="html">
 *   <md-autocomplete
 *       md-selected-item="selectedItem"
 *       md-search-text="searchText"
 *       md-items="item in getMatches(searchText)"
 *       md-item-text="item.display">
 *     <span md-highlight-text="searchText">{{item.display}}</span>
 *   </md-autocomplete>
 * </hljs>
 *
 * ### Example with "not found" message
 * <hljs lang="html">
 * <md-autocomplete
 *     md-selected-item="selectedItem"
 *     md-search-text="searchText"
 *     md-items="item in getMatches(searchText)"
 *     md-item-text="item.display">
 *   <md-item-template>
 *     <span md-highlight-text="searchText">{{item.display}}</span>
 *   </md-item-template>
 *   <md-not-found>
 *     No matches found.
 *   </md-not-found>
 * </md-autocomplete>
 * </hljs>
 *
 * In this example, our code utilizes `md-item-template` and `md-not-found` to specify the
 *     different parts that make up our component.
 *
 * ### Example with validation
 * <hljs lang="html">
 * <form name="autocompleteForm">
 *   <md-autocomplete
 *       required
 *       md-input-name="autocomplete"
 *       md-selected-item="selectedItem"
 *       md-search-text="searchText"
 *       md-items="item in getMatches(searchText)"
 *       md-item-text="item.display">
 *     <md-item-template>
 *       <span md-highlight-text="searchText">{{item.display}}</span>
 *     </md-item-template>
 *     <div ng-messages="autocompleteForm.autocomplete.$error">
 *       <div ng-message="required">This field is required</div>
 *     </div>
 *   </md-autocomplete>
 * </form>
 * </hljs>
 *
 * In this example, our code utilizes `md-item-template` and `ng-messages` to specify
 *     input validation for the field.

   * @description
   * `<md-chips>` is an input component for building lists of strings or objects. The list items are
   * displayed as 'chips'. This component can make use of an `<input>` element or an 
   * `<md-autocomplete>` element.
   *
   * ### Custom templates
   * A custom template may be provided to render the content of each chip. This is achieved by
   * specifying an `<md-chip-template>` element containing the custom content as a child of
   * `<md-chips>`.
   *
   * Note: Any attributes on
   * `<md-chip-template>` will be dropped as only the innerHTML is used for the chip template. The
   * variables `$chip` and `$index` are available in the scope of `<md-chip-template>`, representing
   * the chip object and its index in the list of chips, respectively.
   * To override the chip delete control, include an element (ideally a button) with the attribute
   * `md-chip-remove`. A click listener to remove the chip will be added automatically. The element
   * is also placed as a sibling to the chip content (on which there are also click listeners) to
   * avoid a nested ng-click situation.
   *
   * <h3> Pending Features </h3>

   * @param {string=} secondary-placeholder Placeholder text that will be forwarded to the input,
   *    displayed when there is at least one item in the list

/**
 * @ngdoc directive
 * @name mdIcon
 * @module material.components.icon
 *
 * @restrict E
 *
 * @description
 * The `md-icon` directive makes it easier to use vector-based icons in your app (as opposed to
 * raster-based icons types like PNG). The directive supports both icon fonts and SVG icons.
 *
 * Icons should be considered view-only elements that should not be used directly as buttons; instead nest a `<md-icon>`
 * inside a `md-button` to add hover and click features.
 *
 * ### Icon fonts
 * Icon fonts are a technique in which you use a font where the glyphs in the font are
 * your icons instead of text. Benefits include a straightforward way to bundle everything into a
 * single HTTP request, simple scaling, easy color changing, and more.
 *
 * `md-icon` lets you consume an icon font by letting you reference specific icons in that font
 * by name rather than character code.
 *
 * ### SVG
 * For SVGs, the problem with using `<img>` or a CSS `background-image` is that you can't take
 * advantage of some SVG features, such as styling specific parts of the icon with CSS or SVG
 * animation.
 *
 * `md-icon` makes it easier to use SVG icons by *inlining* the SVG into an `<svg>` element in the
 * document. The most straightforward way of referencing an SVG icon is via URL, just like a
 * traditional `<img>`. `$mdIconProvider`, as a convenience, lets you _name_ an icon so you can
 * reference it by name instead of URL throughout your templates.
 *
 * Additionally, you may not want to make separate HTTP requests for every icon, so you can bundle
 * your SVG icons together and pre-load them with $mdIconProvider as an icon set. An icon set can
 * also be given a name, which acts as a namespace for individual icons, so you can reference them
 * like `"social:cake"`.
 *
 * When using SVGs, both external SVGs (via URLs) or sets of SVGs [from icon sets] can be
 * easily loaded and used.When use font-icons, developers must following three (3) simple steps:
 *
 * <ol>
 * <li>Load the font library. e.g.<br/>
 *    `<link href="https://fonts.googleapis.com/icon?family=Material+Icons"
 *    rel="stylesheet">`
 * </li>
 * <li>
 *   Use either (a) font-icon class names or (b) font ligatures to render the font glyph by using
 *   its textual name
 * </li>
 * <li>
 *   Use `<md-icon md-font-icon="classname" />` or <br/>
 *   use `<md-icon md-font-set="font library classname or alias"> textual_name </md-icon>` or <br/>
 *   use `<md-icon md-font-set="font library classname or alias"> numerical_character_reference </md-icon>`
 * </li>
 * </ol>
 *
 * Full details for these steps can be found:
 *
 * <ul>

 * @param {string} md-font-icon String name of CSS icon associated with the font-face will be used
 * to render the icon. Requires the fonts and the named CSS styles to be preloaded.
 * @param {string} md-font-set CSS style name associated with the font library; which will be assigned as
 * the class for the font-icon ligature. This value may also be an alias that is used to lookup the classname;
 * internally use `$mdIconProvider.fontSet(<alias>)` to determine the style name.
 * @param {string} md-svg-src String URL (or expression) used to load, cache, and display an
 *     external SVG.
 * @param {string} md-svg-icon md-svg-icon String name used for lookup of the icon from the internal cache;
 *     interpolated strings or expressions may also be used. Specific set names can be used with
 *     the syntax `<set name>:<icon name>`.<br/><br/>
 * To use icon sets, developers are required to pre-register the sets using the `$mdIconProvider` service.
 * @param {string=} aria-label Labels icon for accessibility. If an empty string is provided, icon
 * will be hidden from accessibility layer with `aria-hidden="true"`. If there's no aria-label on the icon
 * nor a label on the parent element, a warning will be logged to the console.
 * @param {string=} alt Labels icon for accessibility. If an empty string is provided, icon
 * will be hidden from accessibility layer with `aria-hidden="true"`. If there's no alt on the icon
 * nor a label on the parent element, a warning will be logged to the console.

/**
 * @ngdoc service

 * @module material.components.icon
 *
 * @description
 * `$mdIconProvider` is used only to register icon IDs with URLs. These configuration features allow
 * icons and icon sets to be pre-registered and associated with source URLs **before** the `<md-icon />`
 * directives are compiled.
 *
 * If using font-icons, the developer is responsible for loading the fonts.
 *
 * If using SVGs, loading of the actual svg files are deferred to on-demand requests and are loaded
 * internally by the `$mdIcon` service using the `$templateRequest` service. When an SVG is
 * requested by name/ID, the `$mdIcon` service searches its registry for the associated source URL;
 * that URL is used to on-demand load and parse the SVG dynamically.
 *
 * The `$templateRequest` service expects the icons source to be loaded over trusted URLs.<br/>
 * This means, when loading icons from an external URL, you have to trust the URL in the `$sceDelegateProvider`.
 *
 * <hljs lang="js">
 *   app.config(function($sceDelegateProvider) {
 *     $sceDelegateProvider.resourceUrlWhitelist([
 *       // Adding 'self' to the whitelist, will allow requests from the current origin.

 *       // Using double asterisks here, will allow all URLs to load.
 *       // We recommend to only specify the given domain you want to allow.
 *       '**'
 *     ]);
 *   });
 * </hljs>
 *
 * Read more about the [$sceDelegateProvider](https://docs.angularjs.org/api/ng/provider/$sceDelegateProvider).
 *
 * **Notice:** Most font-icons libraries do not support ligatures (for example `fontawesome`).<br/>
 *  In such cases you are not able to use the icon's ligature name - Like so:
 *
 *  <hljs lang="html">
 *    <md-icon md-font-set="fa">fa-bell</md-icon>
 *  </hljs>
 *
 * You should instead use the given unicode, instead of the ligature name.
 *
 * <p ng-hide="true"> ##// Notice we can't use a hljs element here, because the characters will be escaped.</p>
 *  ```html
 *    <md-icon md-font-set="fa">&#xf0f3</md-icon>
 *  ```
 *
 * All unicode ligatures are prefixed with the `&#x` string.

/**
 * @ngdoc directive
 * @name mdMenu
 * @module material.components.menu
 * @restrict E
 * @description
 *
 * Menus are elements that open when clicked. They are useful for displaying
 * additional options within the context of an action.
 *
 * Every `md-menu` must specify exactly two child elements. The first element is what is
 * left in the DOM and is used to open the menu. This element is called the trigger element.
 * The trigger element's scope has access to `$mdOpenMenu($event)`
 * which it may call to open the menu. By passing $event as argument, the
 * corresponding event is stopped from propagating up the DOM-tree.
 *
 * The second element is the `md-menu-content` element which represents the
 * contents of the menu when it is open. Typically this will contain `md-menu-item`s,
 * but you can do custom content as well.
 *
 * <hljs lang="html">
 * <md-menu>
 *  <!-- Trigger element is a md-button with an icon -->
 *  <md-button ng-click="$mdOpenMenu($event)" class="md-icon-button" aria-label="Open sample menu">
 *    <md-icon md-svg-icon="call:phone"></md-icon>
 *  </md-button>
 *  <md-menu-content>
 *    <md-menu-item><md-button ng-click="doSomething()">Do Something</md-button></md-menu-item>
 *  </md-menu-content>
 * </md-menu>
 * </hljs>

 * ## Sizing Menus
 *
 * The width of the menu when it is open may be specified by specifying a `width`
 * attribute on the `md-menu-content` element.
 * See the [Material Design Spec](https://material.google.com/components/menus.html#menus-simple-menus)
 * for more information.
 *
 *
 * ## Aligning Menus
 *
 * When a menu opens, it is important that the content aligns with the trigger element.
 * Failure to align menus can result in jarring experiences for users as content
 * suddenly shifts. To help with this, `md-menu` provides serveral APIs to help
 * with alignment.
 *
 * ### Target Mode
 *
 * By default, `md-menu` will attempt to align the `md-menu-content` by aligning
 * designated child elements in both the trigger and the menu content.
 *
 * To specify the alignment element in the `trigger` you can use the `md-menu-origin`
 * attribute on a child element. If no `md-menu-origin` is specified, the `md-menu`
 * will be used as the origin element.
 *
 * Similarly, the `md-menu-content` may specify a `md-menu-align-target` for a
 * `md-menu-item` to specify the node that it should try and align with.
 *
 * In this example code, we specify an icon to be our origin element, and an
 * icon in our menu content to be our alignment target. This ensures that both
 * icons are aligned when the menu opens.
 *
 * <hljs lang="html">
 * <md-menu>
 *  <md-button ng-click="$mdOpenMenu($event)" class="md-icon-button" aria-label="Open some menu">
 *    <md-icon md-menu-origin md-svg-icon="call:phone"></md-icon>
 *  </md-button>
 *  <md-menu-content>
 *    <md-menu-item>
 *      <md-button ng-click="doSomething()" aria-label="Do something">
 *        <md-icon md-menu-align-target md-svg-icon="call:phone"></md-icon>
 *        Do Something
 *      </md-button>
 *    </md-menu-item>
 *  </md-menu-content>
 * </md-menu>
 * </hljs>
 *
 * Sometimes we want to specify alignment on the right side of an element, for example
 * if we have a menu on the right side a toolbar, we want to right align our menu content.
 *
 * We can specify the origin by using the `md-position-mode` attribute on both
 * the `x` and `y` axis. Right now only the `x-axis` has more than one option.
 * You may specify the default mode of `target target` or
 * `target-right target` to specify a right-oriented alignment target. See the
 * position section of the demos for more examples.
 *
 * ### Menu Offsets
 *
 * It is sometimes unavoidable to need to have a deeper level of control for
 * the positioning of a menu to ensure perfect alignment. `md-menu` provides
 * the `md-offset` attribute to allow pixel level specificty of adjusting the
 * exact positioning.
 *
 * This offset is provided in the format of `x y` or `n` where `n` will be used
 * in both the `x` and `y` axis.
 *
 * For example, to move a menu by `2px` from the top, we can use:
 * <hljs lang="html">
 * <md-menu md-offset="2 0">
 *   <!-- menu-content -->
 * </md-menu>
 * </hljs>
 *
 * ### Auto Focus
 * By default, when a menu opens, `md-menu` focuses the first button in the menu content.
 * 
 * But sometimes you would like to focus another specific menu item instead of the first.<br/>
 * This can be done by applying the `md-autofocus` directive on the given element.
 *
 * <hljs lang="html">
 * <md-menu-item>
 *   <md-button md-autofocus ng-click="doSomething()">
 *     Auto Focus
 *   </md-button>
 * </md-menu-item>
 * </hljs>
 *
 *
 * ### Preventing close
 *
 * Sometimes you would like to be able to click on a menu item without having the menu
 * close. To do this, ngMaterial exposes the `md-prevent-menu-close` attribute which
 * can be added to a button inside a menu to stop the menu from automatically closing.
 * You can then close the menu programatically by injecting `$mdMenu` and calling 
 * `$mdMenu.hide()`.
 *
 * <hljs lang="html">
 * <md-menu-item>
 *   <md-button ng-click="doSomething()" aria-label="Do something" md-prevent-menu-close="md-prevent-menu-close">
 *     <md-icon md-menu-align-target md-svg-icon="call:phone"></md-icon>
 *     Do Something
 *   </md-button>
 * </md-menu-item>
 * </hljs>
 *
 * @usage
 * <hljs lang="html">
 * <md-menu>
 *  <md-button ng-click="$mdOpenMenu($event)" class="md-icon-button">
 *    <md-icon md-svg-icon="call:phone"></md-icon>
 *  </md-button>
 *  <md-menu-content>
 *    <md-menu-item><md-button ng-click="doSomething()">Do Something</md-button></md-menu-item>
 *  </md-menu-content>
 * </md-menu>
 * </hljs>
 *
 * @param {string} md-position-mode The position mode in the form of
 *           `x`, `y`. Default value is `target`,`target`. Right now the `x` axis
 *           also suppports `target-right`.
 * @param {string} md-offset An offset to apply to the dropdown after positioning
 *           `x`, `y`. Default value is `0`,`0`.

 *
 * ## Menu Bar Controls
 *
 * You may place `md-menu-items` that function as controls within menu bars.
 * There are two modes that are exposed via the `type` attribute of the `md-menu-item`.
 * `type="checkbox"` will function as a boolean control for the `ng-model` attribute of the
 * `md-menu-item`. `type="radio"` will function like a radio button, setting the `ngModel`
 * to the `string` value of the `value` attribute. If you need non-string values, you can use
 * `ng-value` to provide an expression (this is similar to how angular's native `input[type=radio]` works.
 *
 * <hljs lang="html">
 * <md-menu-bar>
 *  <md-menu>
 *    <button ng-click="$mdOpenMenu()">
 *      Sample Menu
 *    </button>
 *    <md-menu-content>
 *      <md-menu-item type="checkbox" ng-model="settings.allowChanges">Allow changes</md-menu-item>
 *      <md-menu-divider></md-menu-divider>
 *      <md-menu-item type="radio" ng-model="settings.mode" ng-value="1">Mode 1</md-menu-item>
 *      <md-menu-item type="radio" ng-model="settings.mode" ng-value="1">Mode 2</md-menu-item>
 *      <md-menu-item type="radio" ng-model="settings.mode" ng-value="1">Mode 3</md-menu-item>
 *    </md-menu-content>
 *  </md-menu>
 * </md-menu-bar>
 * </hljs>
 *
 *
 * ### Nesting Menus
 *
 * Menus may be nested within menu bars. This is commonly called cascading menus.
 * To nest a menu place the nested menu inside the content of the `md-menu-item`.
 * <hljs lang="html">
 * <md-menu-item>
 *   <md-menu>
 *     <button ng-click="$mdOpenMenu()">New</md-button>
 *     <md-menu-content>
 *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Document', $event)">Document</md-button></md-menu-item>
 *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Spreadsheet', $event)">Spreadsheet</md-button></md-menu-item>
 *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Presentation', $event)">Presentation</md-button></md-menu-item>
 *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Form', $event)">Form</md-button></md-menu-item>
 *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Drawing', $event)">Drawing</md-button></md-menu-item>

/**
 * @ngdoc directive
 * @name mdTabs
 * @module material.components.tabs
 *
 * @restrict E
 *
 * @description
 * The `<md-tabs>` directive serves as the container for 1..n `<md-tab>` child directives to
 * produces a Tabs components. In turn, the nested `<md-tab>` directive is used to specify a tab
 * label for the **header button** and a [optional] tab view content that will be associated with
 * each tab button.
 *
 * Below is the markup for its simplest usage:
 *
 *  <hljs lang="html">
 *  <md-tabs>
 *    <md-tab label="Tab #1"></md-tab>
 *    <md-tab label="Tab #2"></md-tab>
 *    <md-tab label="Tab #3"></md-tab>
 *  </md-tabs>
 *  </hljs>
 *
 * Tabs supports three (3) usage scenarios:
 *
 *  1. Tabs (buttons only)
 *  2. Tabs with internal view content
 *  3. Tabs with external view content
 *
 * **Tab-only** support is useful when tab buttons are used for custom navigation regardless of any
 * other components, content, or views.
 *
 * <i><b>Note:</b> If you are using the Tabs component for page-level navigation, please take a look
 * at the <a ng-href="./api/directive/mdNavBar">NavBar component</a> instead as it can handle this
 * case a bit more natively.</i>
 *
 * **Tabs with internal views** are the traditional usages where each tab has associated view
 * content and the view switching is managed internally by the Tabs component.
 *
 * **Tabs with external view content** is often useful when content associated with each tab is
 * independently managed and data-binding notifications announce tab selection changes.
 *
 * Additional features also include:
 *
 * *  Content can include any markup.
 * *  If a tab is disabled while active/selected, then the next tab will be auto-selected.
 *
 * ### Explanation of tab stretching
 *
 * Initially, tabs will have an inherent size.  This size will either be defined by how much space is needed to accommodate their text or set by the user through CSS.  Calculations will be based on this size.
 *
 * On mobile devices, tabs will be expanded to fill the available horizontal space.  When this happens, all tabs will become the same size.
 *
 * On desktops, by default, stretching will never occur.
 *
 * This default behavior can be overridden through the `md-stretch-tabs` attribute.  Here is a table showing when stretching will occur:
 *
 * `md-stretch-tabs` | mobile    | desktop
 * ------------------|-----------|--------
 * `auto`            | stretched | ---
 * `always`          | stretched | stretched
 * `never`           | ---       | ---
 *
 * @param {integer=} md-selected Index of the active/selected tab
 * @param {boolean=} md-no-ink If present, disables ink ripple effects.
 * @param {boolean=} md-no-ink-bar If present, disables the selection ink bar.
 * @param {string=}  md-align-tabs Attribute to indicate position of tab buttons: `bottom` or `top`; default is `top`
 * @param {string=} md-stretch-tabs Attribute to indicate whether or not to stretch tabs: `auto`, `always`, or `never`; default is `auto`
 * @param {boolean=} md-dynamic-height When enabled, the tab wrapper will resize based on the contents of the selected tab
 * @param {boolean=} md-border-bottom If present, shows a solid `1px` border between the tabs and their content
 * @param {boolean=} md-center-tabs When enabled, tabs will be centered provided there is no need for pagination
 * @param {boolean=} md-no-pagination When enabled, pagination will remain off
 * @param {boolean=} md-swipe-content When enabled, swipe gestures will be enabled for the content area to jump between tabs
 * @param {boolean=} md-enable-disconnect When enabled, scopes will be disconnected for tabs that are not being displayed.  This provides a performance boost, but may also cause unexpected issues and is not recommended for most users.
 * @param {boolean=} md-autoselect When present, any tabs added after the initial load will be automatically selected
 * @param {boolean=} md-no-select-click When enabled, click events will not be fired when selecting tabs
 *

 * Returns a new function for [Partial Application](https://en.wikipedia.org/wiki/Partial_application) of the original function.
 *
 * Given a function with N parameters, returns a new function that supports partial application.

 * where M is less than N, it returns a new function that accepts the remaining parameters.  It continues to
 * accept more parameters until all N parameters have been supplied.

 * if an object is found in both arrays.
 * @example
 * ```
 * // returns true if an object is in both of the two arrays
 * function inBoth(array1, array2, object) {
 *   return array1.indexOf(object) !== -1 &&
 *          array2.indexOf(object) !== 1;

 * let bars = [obj3, obj4, obj5]
 *
 * // A curried "copy" of inBoth
 * let curriedInBoth = curry(inBoth);
 * // Partially apply both the array1 and array2
 * let inFoosAndBars = curriedInBoth(foos, bars);
 *
 * // Supply the final argument; since all arguments are
 * // supplied, the original inBoth function is then called.
 * let obj1InBoth = inFoosAndBars(obj1); // false
 *
 * // Use the inFoosAndBars as a predicate.
 * // Filter, on each iteration, supplies the final argument

/**
 * Matches state names using glob-like pattern strings.
 *
 * Globs can be used in specific APIs including:
 *
 * - [[StateService.is]]
 * - [[StateService.includes]]
 * - The first argument to Hook Registration functions like [[TransitionService.onStart]]
 *    - [[HookMatchCriteria]] and [[HookMatchCriterion]]
 *
 * A `Glob` string is a pattern which matches state names.
 * Nested state names are split into segments (separated by a dot) when processing.
 * The state named `foo.bar.baz` is split into three segments ['foo', 'bar', 'baz']
 *
 * Globs work according to the following rules:
 *
 * ### Exact match:
 *
 * The glob `'A.B'` matches the state named exactly `'A.B'`.
 *
 * | Glob        |Matches states named|Does not match state named|
 * |:------------|:--------------------|:---------------------|
 * | `'A'`       | `'A'`               | `'B'` , `'A.C'`      |
 * | `'A.B'`     | `'A.B'`             | `'A'` , `'A.B.C'`    |
 * | `'foo'`     | `'foo'`             | `'FOO'` , `'foo.bar'`|
 *
 * ### Single star (`*`)
 *
 * A single star (`*`) is a wildcard that matches exactly one segment.
 *
 * | Glob        |Matches states named  |Does not match state named |
 * |:------------|:---------------------|:--------------------------|
 * | `'*'`       | `'A'` , `'Z'`        | `'A.B'` , `'Z.Y.X'`       |
 * | `'A.*'`     | `'A.B'` , `'A.C'`    | `'A'` , `'A.B.C'`         |
 * | `'A.*.*'`   | `'A.B.C'` , `'A.X.Y'`| `'A'`, `'A.B'` , `'Z.Y.X'`|
 *
 * ### Double star (`**`)
 *
 * A double star (`'**'`) is a wildcard that matches *zero or more segments*
 *
 * | Glob        |Matches states named                           |Does not match state named         |
 * |:------------|:----------------------------------------------|:----------------------------------|
 * | `'**'`      | `'A'` , `'A.B'`, `'Z.Y.X'`                    | (matches all states)              |
 * | `'A.**'`    | `'A'` , `'A.B'` , `'A.C.X'`                   | `'Z.Y.X'`                         |
 * | `'**.X'`    | `'X'` , `'A.X'` , `'Z.Y.X'`                   | `'A'` , `'A.login.Z'`             |
 * | `'A.**.X'`  | `'A.X'` , `'A.B.X'` , `'A.B.C.X'`             | `'A'` , `'A.B.C'`                 |

     *
     * When a transition is created, the nodes in the "To Path" are injected from a ResolveContext.

     * This method is used to create a narrower context when injecting ancestor nodes.
     *
     * @example
     * `let ABCD = new ResolveContext([A, B, C, D]);`
     *
     * Given a path `[A, B, C, D]`, where `A`, `B`, `C` and `D` are nodes for states `a`, `b`, `c`, `d`:
     * When injecting `D`, `D` should have access to all resolvables from `A`, `B`, `C`, `D`.
     * However, `B` should only be able to access resolvables from `A`, `B`.
     *
     * When resolving for the `B` node, first take the full "To Path" Context `[A,B,C,D]` and limit to the subpath `[A,B]`.
     * `let AB = ABCD.subcontext(a)`

    /**
     * Creates a [[UIInjector]] Dependency Injector
     *
     * Returns a Dependency Injector for the Transition's target state (to state).
     * The injector provides resolve values which the target state has access to.
     *
     * The `UIInjector` can also provide values from the native root/global injector (ng1/ng2).
     *
     * #### Example:
     * ```js
     * .onEnter({ entering: 'myState' }, trans => {
     *   var myResolveValue = trans.injector().get('myResolve');
     *   // Inject a global service from the global/native injector (if it exists)
     *   var MyService = trans.injector().get('MyService');
     * })
     * ```
     *
     * In some cases (such as `onBefore`), you may need access to some resolve data but it has not yet been fetched.
     * You can use [[UIInjector.getAsync]] to get a promise for the data.
     * #### Example:
     * ```js
     * .onBefore({}, trans => {
     *   return trans.injector().getAsync('myResolve').then(myResolveValue =>
     *     return myResolveValue !== 'ABORT';
     *   });
     * });
     * ```
     *
     * If a `state` is provided, the injector that is returned will be limited to resolve values that the provided state has access to.
     * This can be useful if both a parent state `foo` and a child state `foo.bar` have both defined a resolve such as `data`.
     * #### Example:
     * ```js
     * .onEnter({ to: 'foo.bar' }, trans => {
     *   // returns result of `foo` state's `data` resolve
     *   // even though `foo.bar` also has a `data` resolve
     *   var fooData = trans.injector('foo').get('data');
     * });
     * ```
     *
     * If you need resolve data from the exiting states, pass `'from'` as `pathName`.
     * The resolve data from the `from` path will be returned.
     * #### Example:
     * ```js
     * .onExit({ exiting: 'foo.bar' }, trans => {
     *   // Gets the resolve value of `data` from the exiting state.
     *   var fooData = trans.injector(null, 'foo.bar').get('data');
     * });
     * ```
     *
     *
     * @param state Limits the resolves provided to only the resolves the provided state has access to.
     * @param pathName Default: `'to'`: Chooses the path for which to create the injector. Use this to access resolves for `exiting` states.
     *
     * @returns a [[UIInjector]]

     * This returns all the tokens defined on [[StateDeclaration.resolve]] blocks, for the states
     * in the Transition's [[TreeChanges.to]] path.

     * #### Example:

     * ```js
     * let tokens = trans.getResolveTokens();
     * tokens.forEach(token => console.log(token + " = " + trans.injector().get(token)));

     * ```js

     * let promise = tokens.map(token => trans.injector().getAsync(token));

/**
 * Matches URLs against patterns.
 *
 * Matches URLs against patterns and extracts named parameters from the path or the search
 * part of the URL.
 *
 * A URL pattern consists of a path pattern, optionally followed by '?' and a list of search (query)
 * parameters. Multiple search parameter names are separated by '&'. Search parameters
 * do not influence whether or not a URL is matched, but their values are passed through into
 * the matched parameters returned by [[UrlMatcher.exec]].
 *
 * - *Path parameters* are defined using curly brace placeholders (`/somepath/{param}`)
 * or colon placeholders (`/somePath/:param`).
 *
 * - *A parameter RegExp* may be defined for a param after a colon
 * (`/somePath/{param:[a-zA-Z0-9]+}`) in a curly brace placeholder.
 * The regexp must match for the url to be matched.
 * Should the regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
 *
 * Note: a RegExp parameter will encode its value using either [[ParamTypes.path]] or [[ParamTypes.query]].
 *
 * - *Custom parameter types* may also be specified after a colon (`/somePath/{param:int}`) in curly brace parameters.
 *   See [[UrlMatcherFactory.type]] for more information.
 *
 * - *Catch-all parameters* are defined using an asterisk placeholder (`/somepath/*catchallparam`).
 *   A catch-all * parameter value will contain the remainder of the URL.
 *
 * ---
 *
 * Parameter names may contain only word characters (latin letters, digits, and underscore) and
 * must be unique within the pattern (across both path and search parameters).
 * A path parameter matches any number of characters other than '/'. For catch-all
 * placeholders the path parameter matches any number of characters.
 *
 * Examples:
 *
 * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
 *   trailing slashes, and patterns have to match the entire path, not just a prefix.
 * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
 *   '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
 * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
 * * `'/user/{id:[^/]*}'` - Same as the previous example.
 * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
 *   parameter consists of 1 to 8 hex digits.
 * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
 *   path into the parameter 'path'.
 * * `'/files/*path'` - ditto.
 * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
 *   in the built-in  `date` ParamType matches `2014-11-12`) and provides a Date object in $stateParams.start

/**
 * Given a ui-view and a ViewConfig, determines if they "match".
 *
 * A ui-view has a fully qualified name (fqn) and a context object.  The fqn is built from its overall location in
 * the DOM, describing its nesting relationship to any parent ui-view tags it is nested inside of.
 *
 * A ViewConfig has a target ui-view name and a context anchor.  The ui-view name can be a simple name, or
 * can be a segmented ui-view path, describing a portion of a ui-view fqn.
 *
 * In order for a ui-view to match ViewConfig, ui-view's $type must match the ViewConfig's $type
 *
 * If the ViewConfig's target ui-view name is a simple name (no dots), then a ui-view matches if:
 * - the ui-view's name matches the ViewConfig's target name
 * - the ui-view's context matches the ViewConfig's anchor
 *
 * If the ViewConfig's target ui-view name is a segmented name (with dots), then a ui-view matches if:
 * - There exists a parent ui-view where:
 *    - the parent ui-view's name matches the first segment (index 0) of the ViewConfig's target name
 *    - the parent ui-view's context matches the ViewConfig's anchor
 * - And the remaining segments (index 1..n) of the ViewConfig's target name match the tail of the ui-view's fqn
 *
 * Example:
 *
 * DOM:
 * <ui-view>                        <!-- created in the root context (name: "") -->
 *   <ui-view name="foo">                <!-- created in the context named: "A"      -->
 *     <ui-view>                    <!-- created in the context named: "A.B"    -->
 *       <ui-view name="bar">            <!-- created in the context named: "A.B.C"  -->
 *       </ui-view>
 *     </ui-view>
 *   </ui-view>
 * </ui-view>
 *
 * uiViews: [
 *  { fqn: "$default",                  creationContext: { name: "" } },
 *  { fqn: "$default.foo",              creationContext: { name: "A" } },
 *  { fqn: "$default.foo.$default",     creationContext: { name: "A.B" } }
 *  { fqn: "$default.foo.$default.bar", creationContext: { name: "A.B.C" } }
 * ]
 *
 * These four view configs all match the ui-view with the fqn: "$default.foo.$default.bar":
 *
 * - ViewConfig1: { uiViewName: "bar",                       uiViewContextAnchor: "A.B.C" }
 * - ViewConfig2: { uiViewName: "$default.bar",              uiViewContextAnchor: "A.B" }
 * - ViewConfig3: { uiViewName: "foo.$default.bar",          uiViewContextAnchor: "A" }
 * - ViewConfig4: { uiViewName: "$default.foo.$default.bar", uiViewContextAnchor: "" }
 *
 * Using ViewConfig3 as an example, it matches the ui-view with fqn "$default.foo.$default.bar" because:
 * - The ViewConfig's segmented target name is: [ "foo", "$default", "bar" ]
 * - There exists a parent ui-view (which has fqn: "$default.foo") where:
 *    - the parent ui-view's name "foo" matches the first segment "foo" of the ViewConfig's target name
 *    - the parent ui-view's context "A" matches the ViewConfig's anchor context "A"
 * - And the remaining segments [ "$default", "bar" ].join("."_ of the ViewConfig's target name match
 *   the tail of the ui-view's fqn "default.bar"

     * Adds a plugin to UI-Router
     *
     * This method adds a UI-Router Plugin.
     * A plugin can enhance or change UI-Router behavior using any public API.
     *
     * #### Example:
     * ```js
     * import { MyCoolPlugin } from "ui-router-cool-plugin";
     *
     * var plugin = router.addPlugin(MyCoolPlugin);
     * ```
     *
     * ### Plugin authoring
     *
     * A plugin is simply a class (or constructor function) which accepts a [[UIRouter]] instance and (optionally) an options object.
     *
     * The plugin can implement its functionality using any of the public APIs of [[UIRouter]].
     * For example, it may configure router options or add a Transition Hook.
     *
     * The plugin can then be published as a separate module.
     *
     * #### Example:
     * ```js
     * export class MyAuthPlugin implements UIRouterPlugin {
     *   constructor(router: UIRouter, options: any) {
     *     this.name = "MyAuthPlugin";
     *     let $transitions = router.transitionService;
     *     let $state = router.stateService;
     *
     *     let authCriteria = {
     *       to: (state) => state.data && state.data.requiresAuth
     *     };
     *
     *     function authHook(transition: Transition) {
     *       let authService = transition.injector().get('AuthService');
     *       if (!authService.isAuthenticated()) {
     *         return $state.target('login');
     *       }
     *     }
     *
     *     $transitions.onStart(authCriteria, authHook);
     *   }
     * }
     * ```
     *
     * @param plugin one of:
     *        - a plugin class which implements [[UIRouterPlugin]]
     *        - a constructor function for a [[UIRouterPlugin]] which accepts a [[UIRouter]] instance
     *        - a factory function which accepts a [[UIRouter]] instance and returns a [[UIRouterPlugin]] instance

     * Convenience method for transitioning to a new state.
     *
     * `$state.go` calls `$state.transitionTo` internally but automatically sets options to
     * `{ location: true, inherit: true, relative: router.globals.$current, notify: true }`.
     * This allows you to use either an absolute or relative `to` argument (because of `relative: router.globals.$current`).

     * Some examples:

     * - `$state.go('contact.detail')` - will go to the `contact.detail` state
     * - `$state.go('^')` - will go to the parent state
     * - `$state.go('^.sibling')` - if current state is `home.child`, will go to the `home.sibling` state
     * - `$state.go('.child.grandchild')` - if current state is home, will go to the `home.child.grandchild` state
     *
     * @param params A map of the parameters that will be sent to the state, will populate $stateParams.
     *
     *    Any parameters that are not specified will be inherited from current parameter values (because of `inherit: true`).
     *    This allows, for example, going to a sibling state that shares parameters defined by a parent state.

 * A basic angular1-like injector api

 * This object provides a naive implementation of a globally scoped dependency injection system.

 * ### Function parameter names
 *
 * A function's `.toString()` is called, and the parameter names are parsed.

 *
 * ```js
 * function injectedFunction(FooService, BarService) {

 *
 * ### Function annotation
 *
 * A function may be annotated with an array of dependency names as the `$inject` property.
 *
 * ```js
 * injectedFunction.$inject = [ 'FooService', 'BarService' ];
 * function injectedFunction(fs, bs) {
 *   // FooService and BarService are injected as fs and bs parameters
 * }
 * ```
 *
 * ### Array notation
 *
 * An array provides the names of the dependencies to inject (as strings).
 * The function is the last element of the array.
 *
 * ```js
 * [ 'FooService', 'BarService', function (fs, bs) {
 *   // FooService and BarService are injected as fs and bs parameters
 * }]

 * The Angular 1 `StateProvider`

 *
 * A state corresponds to a "place" in the application in terms of the overall UI and
 * navigation. A state describes (via the controller / template / view properties) what
 * the UI looks like and does at that place.
 *
 * States often have things in common, and the primary way of factoring out these
 * commonalities in this model is via the state hierarchy, i.e. parent/child states aka
 * nested states.
 *
 * The `$stateProvider` provides interfaces to declare these states for your app.
 */
var StateProvider = (function () {

    /**
     * Decorates states when they are registered
     *
     * Allows you to extend (carefully) or override (at your own peril) the
     * `stateBuilder` object used internally by [[StateRegistry]].
     * This can be used to add custom functionality to ui-router,
     * for example inferring templateUrl based on the state name.
     *
     * When passing only a name, it returns the current (original or decorated) builder
     * function that matches `name`.
     *
     * The builder functions that can be decorated are listed below. Though not all
     * necessarily have a good use case for decoration, that is up to you to decide.
     *
     * In addition, users can attach custom decorators, which will generate new
     * properties within the state's internal definition. There is currently no clear
     * use-case for this beyond accessing internal states (i.e. $state.$current),
     * however, expect this to become increasingly relevant as we introduce additional
     * meta-programming features.
     *
     * **Warning**: Decorators should not be interdependent because the order of
     * execution of the builder functions in non-deterministic. Builder functions
     * should only be dependent on the state definition object and super function.
     *
     *
     * Existing builder functions and current return values:
     *
     * - **parent** `{object}` - returns the parent state object.
     * - **data** `{object}` - returns state data, including any inherited data that is not
     *   overridden by own values (if any).
     * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
     *   or `null`.
     * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is
     *   navigable).
     * - **params** `{object}` - returns an array of state params that are ensured to
     *   be a super-set of parent's params.
     * - **views** `{object}` - returns a views object where each key is an absolute view
     *   name (i.e. "viewName@stateName") and each value is the config object
     *   (template, controller) for the view. Even when you don't use the views object
     *   explicitly on a state config, one is still created for you internally.
     *   So by decorating this builder function you have access to decorating template
     *   and controller properties.
     * - **ownParams** `{object}` - returns an array of params that belong to the state,
     *   not including any params defined by ancestor states.
     * - **path** `{string}` - returns the full path from the root down to this state.
     *   Needed for state activation.
     * - **includes** `{object}` - returns an object that includes every state that
     *   would pass a `$state.includes()` test.
     *
     * #### Example:
     * Override the internal 'views' builder with a function that takes the state
     * definition, and a reference to the internal function being overridden:
     * ```js
     * $stateProvider.decorator('views', function (state, parent) {
     *   let result = {},
     *       views = parent(state);
     *
     *   angular.forEach(views, function (config, name) {
     *     let autoName = (state.name + '.' + name).replace('.', '/');
     *     config.templateUrl = config.templateUrl || '/partials/' + autoName + '.html';
     *     result[name] = config;
     *   });
     *   return result;
     * });
     *
     * $stateProvider.state('home', {
     *   views: {
     *     'contact.list': { controller: 'ListController' },
     *     'contact.item': { controller: 'ItemController' }
     *   }
     * });
     * ```
     *
     *
     * ```js
     * // Auto-populates list and item views with /partials/home/contact/list.html,
     * // and /partials/home/contact/item.html, respectively.
     * $state.go('home');
     * ```
     *
     * @param {string} name The name of the builder function to decorate.
     * @param {object} func A function that is responsible for decorating the original
     * builder function. The function receives two parameters:

     *   // Prevent $urlRouter from automatically intercepting URL changes;

     *     $urlRouter.listen();
     *     $urlRouter.sync();
     *   });
     * });
     * ```
     *
     * @param defer Indicates whether to defer location change interception.
     *        Passing no parameter is equivalent to `true`.

/**
 * # Angular 1 injectable services
 *
 * This is a list of the objects which can be injected using angular's injector.
 *
 * There are three different kind of injectable objects:
 *
 * ## **Provider** objects
 * #### injectable into a `.config()` block during configtime
 *
 * - [[$uiRouterProvider]]: The UI-Router instance
 * - [[$stateProvider]]: State registration
 * - [[$transitionsProvider]]: Transition hooks
 * - [[$urlServiceProvider]]: All URL related public APIs
 *
 * - [[$uiViewScrollProvider]]: Disable ui-router view scrolling
 * - [[$urlRouterProvider]]: (deprecated) Url matching rules
 * - [[$urlMatcherFactoryProvider]]: (deprecated) Url parsing config
 *
 * ## **Service** objects
 * #### injectable globally during runtime
 *
 * - [[$uiRouter]]: The UI-Router instance
 * - [[$trace]]: Enable transition trace/debug
 * - [[$transitions]]: Transition hooks
 * - [[$state]]: Imperative state related APIs
 * - [[$stateRegistry]]: State registration
 * - [[$urlService]]: All URL related public APIs
 * - [[$uiRouterGlobals]]: Global variables
 * - [[$uiViewScroll]]: Scroll an element into view
 *
 * - [[$stateParams]]: (deprecated) Global state param values
 * - [[$urlRouter]]: (deprecated) URL synchronization
 * - [[$urlMatcherFactory]]: (deprecated) URL parsing config
 *
 * ## **Per-Transition** objects
 *
 * - These kind of objects are injectable into:
 *   - Resolves ([[Ng1StateDeclaration.resolve]]),
 *   - Transition Hooks ([[TransitionService.onStart]], etc),
 *   - Routed Controllers ([[Ng1ViewDeclaration.controller]])
 *
 * #### Different instances are injected based on the [[Transition]]
 *
 * - [[$transition$]]: The current Transition object
 * - [[$stateParams]]: State param values for pending Transition (deprecated)
 * - Any resolve data defined using [[Ng1StateDeclaration.resolve]]

/**
 * The current (or pending) State Parameters
 *
 * An injectable global **Service Object** which holds the state parameters for the latest **SUCCESSFUL** transition.
 *
 * The values are not updated until *after* a `Transition` successfully completes.
 *
 * **Also:** an injectable **Per-Transition Object** object which holds the pending state parameters for the pending `Transition` currently running.
 *
 * ### Deprecation warning:
 *
 * The value injected for `$stateParams` is different depending on where it is injected.
 *
 * - When injected into an angular service, the object injected is the global **Service Object** with the parameter values for the latest successful `Transition`.
 * - When injected into transition hooks, resolves, or view controllers, the object is the **Per-Transition Object** with the parameter values for the running `Transition`.
 *
 * Because of these confusing details, this service is deprecated.
 *
 * ### Instead of using the global `$stateParams` service object,
 * inject [[$uiRouterGlobals]] and use [[UIRouterGlobals.params]]
 *
 * ```js
 * MyService.$inject = ['$uiRouterGlobals'];
 * function MyService($uiRouterGlobals) {
 *   return {
 *     paramValues: function () {
 *       return $uiRouterGlobals.params;
 *     }
 *   }
 * }
 * ```
 *
 * ### Instead of using the per-transition `$stateParams` object,
 * inject the current `Transition` (as [[$transition$]]) and use [[Transition.params]]
 *
 * ```js
 * MyController.$inject = ['$transition$'];
 * function MyController($transition$) {
 *   var username = $transition$.params().username;
 *   // .. do something with username
 * }
 * ```
 *
 * ---
 *
 * This object can be injected into other services.
 *
 * #### Deprecated Example:
 * ```js
 * SomeService.$inject = ['$http', '$stateParams'];
 * function SomeService($http, $stateParams) {
 *   return {
 *     getUser: function() {
 *       return $http.get('/api/users/' + $stateParams.username);
 *     }
 *   }
 * };
 * angular.service('SomeService', SomeService);

/**
 * `ui-sref`: A directive for linking to a state
 *
 * A directive which links to a state (and optionally, parameters).
 * When clicked, this directive activates the linked state with the supplied parameter values.
 *
 * ### Linked State
 * The attribute value of the `ui-sref` is the name of the state to link to.
 *
 * #### Example:
 * This will activate the `home` state when the link is clicked.
 * ```html
 * <a ui-sref="home">Home</a>
 * ```
 *
 * ### Relative Links
 * You can also use relative state paths within `ui-sref`, just like a relative path passed to `$state.go()` ([[StateService.go]]).
 * You just need to be aware that the path is relative to the state that *created* the link.
 * This allows a state to create a relative `ui-sref` which always targets the same destination.
 *
 * #### Example:
 * Both these links are relative to the parent state, even when a child state is currently active.
 * ```html
 * <a ui-sref=".child1">child 1 state</a>
 * <a ui-sref=".child2">child 2 state</a>
 * ```
 *
 * This link activates the parent state.
 * ```html
 * <a ui-sref="^">Return</a>
 * ```
 *
 * ### hrefs
 * If the linked state has a URL, the directive will automatically generate and
 * update the `href` attribute (using the [[StateService.href]]  method).
 *
 * #### Example:
 * Assuming the `users` state has a url of `/users/`
 * ```html
 * <a ui-sref="users" href="/users/">Users</a>
 * ```
 *
 * ### Parameter Values
 * In addition to the state name, a `ui-sref` can include parameter values which are applied when activating the state.
 * Param values can be provided in the `ui-sref` value after the state name, enclosed by parentheses.
 * The content inside the parentheses is an expression, evaluated to the parameter values.
 *
 * #### Example:
 * This example renders a list of links to users.
 * The state's `userId` parameter value comes from each user's `user.id` property.
 * ```html
 * <li ng-repeat="user in users">
 *   <a ui-sref="users.detail({ userId: user.id })">{{ user.displayName }}</a>
 * </li>
 * ```
 *
 * Note:
 * The parameter values expression is `$watch`ed for updates.
 *
 * ### Transition Options
 * You can specify [[TransitionOptions]] to pass to [[StateService.go]] by using the `ui-sref-opts` attribute.
 * Options are restricted to `location`, `inherit`, and `reload`.
 *
 * #### Example:
 * ```html
 * <a ui-sref="home" ui-sref-opts="{ reload: true }">Home</a>
 * ```
 *
 * ### Other DOM Events
 *
 * You can also customize which DOM events to respond to (instead of `click`) by
 * providing an `events` array in the `ui-sref-opts` attribute.
 *
 * #### Example:
 * ```html
 * <input type="text" ui-sref="contacts" ui-sref-opts="{ events: ['change', 'blur'] }">
 * ```
 *
 * ### Highlighting the active link
 * This directive can be used in conjunction with [[uiSrefActive]] to highlight the active link.
 *
 * ### Examples
 * If you have the following template:
 *
 * ```html
 * <a ui-sref="home">Home</a>
 * <a ui-sref="about">About</a>
 * <a ui-sref="{page: 2}">Next page</a>
 *
 * <ul>
 *     <li ng-repeat="contact in contacts">
 *         <a ui-sref="contacts.detail({ id: contact.id })">{{ contact.name }}</a>
 *     </li>
 * </ul>
 * ```
 *
 * Then (assuming the current state is `contacts`) the rendered html including hrefs would be:
 *
 * ```html
 * <a href="#/home" ui-sref="home">Home</a>
 * <a href="#/about" ui-sref="about">About</a>
 * <a href="#/contacts?page=2" ui-sref="{page: 2}">Next page</a>
 *
 * <ul>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/1" ui-sref="contacts.detail({ id: contact.id })">Joe</a>
 *     </li>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/2" ui-sref="contacts.detail({ id: contact.id })">Alice</a>
 *     </li>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/3" ui-sref="contacts.detail({ id: contact.id })">Bob</a>
 *     </li>
 * </ul>
 *
 * <a href="#/home" ui-sref="home" ui-sref-opts="{reload: true}">Home</a>
 * ```
 *
 * ### Notes
 *
 * - You can use `ui-sref` to change **only the parameter values** by omitting the state name and parentheses.
 * #### Example:
 * Sets the `lang` parameter to `en` and remains on the same state.
 *
 * ```html
 * <a ui-sref="{ lang: 'en' }">English</a>
 * ```
 *
 * - A middle-click, right-click, or ctrl-click is handled (natively) by the browser to open the href in a new window, for example.
 *
 * - Unlike the parameter values expression, the state name is not `$watch`ed (for performance reasons).
 * If you need to dynamically update the state being linked to, use the fully dynamic [[uiState]] directive.

/**
 * `ui-state`: A fully dynamic directive for linking to a state
 *
 * A directive which links to a state (and optionally, parameters).
 * When clicked, this directive activates the linked state with the supplied parameter values.
 *
 * **This directive is very similar to [[uiSref]], but it `$observe`s and `$watch`es/evaluates all its inputs.**
 *
 * A directive which links to a state (and optionally, parameters).
 * When clicked, this directive activates the linked state with the supplied parameter values.
 *
 * ### Linked State
 * The attribute value of `ui-state` is an expression which is `$watch`ed and evaluated as the state to link to.
 * **This is in contrast with `ui-sref`, which takes a state name as a string literal.**
 *
 * #### Example:
 * Create a list of links.
 * ```html
 * <li ng-repeat="link in navlinks">
 *   <a ui-state="link.state">{{ link.displayName }}</a>
 * </li>
 * ```
 *
 * ### Relative Links
 * If the expression evaluates to a relative path, it is processed like [[uiSref]].
 * You just need to be aware that the path is relative to the state that *created* the link.
 * This allows a state to create relative `ui-state` which always targets the same destination.
 *
 * ### hrefs
 * If the linked state has a URL, the directive will automatically generate and
 * update the `href` attribute (using the [[StateService.href]]  method).
 *
 * ### Parameter Values
 * In addition to the state name expression, a `ui-state` can include parameter values which are applied when activating the state.
 * Param values should be provided using the `ui-state-params` attribute.
 * The `ui-state-params` attribute value is `$watch`ed and evaluated as an expression.
 *
 * #### Example:
 * This example renders a list of links with param values.
 * The state's `userId` parameter value comes from each user's `user.id` property.
 * ```html
 * <li ng-repeat="link in navlinks">
 *   <a ui-state="link.state" ui-state-params="link.params">{{ link.displayName }}</a>
 * </li>
 * ```
 *
 * ### Transition Options
 * You can specify [[TransitionOptions]] to pass to [[StateService.go]] by using the `ui-state-opts` attribute.
 * Options are restricted to `location`, `inherit`, and `reload`.
 * The value of the `ui-state-opts` is `$watch`ed and evaluated as an expression.
 *
 * #### Example:
 * ```html
 * <a ui-state="returnto.state" ui-state-opts="{ reload: true }">Home</a>
 * ```
 *
 * ### Other DOM Events
 *
 * You can also customize which DOM events to respond to (instead of `click`) by
 * providing an `events` array in the `ui-state-opts` attribute.
 *
 * #### Example:
 * ```html
 * <input type="text" ui-state="contacts" ui-state-opts="{ events: ['change', 'blur'] }">
 * ```
 *
 * ### Highlighting the active link
 * This directive can be used in conjunction with [[uiSrefActive]] to highlight the active link.
 *
 * ### Notes
 *
 * - You can use `ui-params` to change **only the parameter values** by omitting the state name and supplying only `ui-state-params`.
 *   However, it might be simpler to use [[uiSref]] parameter-only links.
 *
 * #### Example:
 * Sets the `lang` parameter to `en` and remains on the same state.
 *
 * ```html
 * <a ui-state="" ui-state-params="{ lang: 'en' }">English</a>
 * ```
 *
 * - A middle-click, right-click, or ctrl-click is handled (natively) by the browser to open the href in a new window, for example.
 * ```

/**
 * `ui-sref-active` and `ui-sref-active-eq`: A directive that adds a CSS class when a `ui-sref` is active
 *
 * A directive working alongside [[uiSref]] and [[uiState]] to add classes to an element when the
 * related directive's state is active (and remove them when it is inactive).
 *
 * The primary use-case is to highlight the active link in navigation menus,
 * distinguishing it from the inactive menu items.
 *
 * ### Linking to a `ui-sref` or `ui-state`
 * `ui-sref-active` can live on the same element as `ui-sref`/`ui-state`, or it can be on a parent element.
 * If a `ui-sref-active` is a parent to more than one `ui-sref`/`ui-state`, it will apply the CSS class when **any of the links are active**.
 *
 * ### Matching
 *
 * The `ui-sref-active` directive applies the CSS class when the `ui-sref`/`ui-state`'s target state **or any child state is active**.
 * This is a "fuzzy match" which uses [[StateService.includes]].
 *
 * The `ui-sref-active-eq` directive applies the CSS class when the `ui-sref`/`ui-state`'s target state is directly active (not when child states are active).
 * This is an "exact match" which uses [[StateService.is]].
 *
 * ### Parameter values
 * If the `ui-sref`/`ui-state` includes parameter values, the current parameter values must match the link's values for the link to be highlighted.
 * This allows a list of links to the same state with different parameters to be rendered, and the correct one highlighted.
 *
 * #### Example:
 * ```html
 * <li ng-repeat="user in users" ui-sref-active="active">
 *   <a ui-sref="user.details({ userId: user.id })">{{ user.lastName }}</a>
 * </li>
 * ```
 *
 * ### Examples
 *
 * Given the following template:
 * #### Example:
 * ```html
 * <ul>
 *   <li ui-sref-active="active" class="item">
 *     <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
 *   </li>
 * </ul>
 * ```
 *
 * When the app state is `app.user` (or any child state),
 * and contains the state parameter "user" with value "bilbobaggins",
 * the resulting HTML will appear as (note the 'active' class):
 *
 * ```html
 * <ul>
 *   <li ui-sref-active="active" class="item active">
 *     <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
 *   </li>
 * </ul>
 * ```
 *
 * ### Glob mode
 *
 * It is possible to pass `ui-sref-active` an expression that evaluates to an object.
 * The objects keys represent active class names and values represent the respective state names/globs.
 * `ui-sref-active` will match if the current active state **includes** any of
 * the specified state names/globs, even the abstract ones.
 *
 * #### Example:
 * Given the following template, with "admin" being an abstract state:
 * ```html
 * <div ui-sref-active="{'active': 'admin.**'}">
 *   <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
 * </div>
 * ```
 *
 * When the current state is "admin.roles" the "active" class will be applied to both the <div> and <a> elements.
 * It is important to note that the state names/globs passed to `ui-sref-active` override any state provided by a linked `ui-sref`.
 *
 * ### Notes:
 *
 * - The class name is interpolated **once** during the directives link time (any further changes to the
 * interpolated value are ignored).
 *
 * - Multiple classes may be specified in a space-separated format: `ui-sref-active='class1 class2 class3'`

/**
 * `ui-view`: A viewport directive which is filled in by a view from the active state.
 *
 * ### Attributes
 *
 * - `name`: (Optional) A view name.
 *   The name should be unique amongst the other views in the same state.
 *   You can have views of the same name that live in different states.
 *   The ui-view can be targeted in a View using the name ([[Ng1StateDeclaration.views]]).
 *
 * - `autoscroll`: an expression. When it evaluates to true, the `ui-view` will be scrolled into view when it is activated.
 *   Uses [[$uiViewScroll]] to do the scrolling.
 *
 * - `onload`: Expression to evaluate whenever the view updates.
 *
 * #### Example:
 * A view can be unnamed or named.
 * ```html
 * <!-- Unnamed -->
 * <div ui-view></div>
 *
 * <!-- Named -->
 * <div ui-view="viewName"></div>
 *
 * <!-- Named (different style) -->
 * <ui-view name="viewName"></ui-view>
 * ```
 *
 * You can only have one unnamed view within any template (or root html). If you are only using a
 * single view and it is unnamed then you can populate it like so:
 *
 * ```html
 * <div ui-view></div>
 * $stateProvider.state("home", {
 *   template: "<h1>HELLO!</h1>"
 * })
 * ```
 *
 * The above is a convenient shortcut equivalent to specifying your view explicitly with the
 * [[Ng1StateDeclaration.views]] config property, by name, in this case an empty name:
 *
 * ```js
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }
 * })
 * ```
 *
 * But typically you'll only use the views property if you name your view or have more than one view
 * in the same template. There's not really a compelling reason to name a view if its the only one,
 * but you could if you wanted, like so:
 *
 * ```html
 * <div ui-view="main"></div>
 * ```
 *
 * ```js
 * $stateProvider.state("home", {
 *   views: {
 *     "main": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }
 * })
 * ```
 *
 * Really though, you'll use views to set up multiple views:
 *
 * ```html
 * <div ui-view></div>
 * <div ui-view="chart"></div>
 * <div ui-view="data"></div>
 * ```
 *
 * ```js
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     },
 *     "chart": {
 *       template: "<chart_thing/>"
 *     },
 *     "data": {
 *       template: "<data_thing/>"
 *     }
 *   }
 * })
 * ```
 *
 * #### Examples for `autoscroll`:
 * ```html
 * <!-- If autoscroll present with no expression,
 *      then scroll ui-view into view -->
 * <ui-view autoscroll/>
 *
 * <!-- If autoscroll present with valid expression,
 *      then scroll ui-view into view if expression evaluates to true -->
 * <ui-view autoscroll='true'/>
 * <ui-view autoscroll='false'/>
 * <ui-view autoscroll='scopeVariable'/>
 * ```
 *
 * Resolve data:
 *
 * The resolved data from the state's `resolve` block is placed on the scope as `$resolve` (this
 * can be customized using [[Ng1ViewDeclaration.resolveAs]]).  This can be then accessed from the template.
 *
 * Note that when `controllerAs` is being used, `$resolve` is set on the controller instance *after* the
 * controller is instantiated.  The `$onInit()` hook can be used to perform initialization code which
 * depends on `$resolve` data.
 *
 * #### Example:
 * ```js
 * $stateProvider.state('home', {
 *   template: '<my-component user="$resolve.user"></my-component>',
 *   resolve: {
 *     user: function(UserService) { return UserService.fetchUser(); }
 *   }
 * });
 * ```

             * Our basic approach here for event handlers is that we listen for a down event (mousedown or touchstart).
             * Once we have a down event, we need to work out whether we have a click, a drag, or a
             * hold.  A click would sort the grid (if sortable).  A drag would be used by moveable, so
             * we ignore it.  A hold would open the menu.
             *
             * So, on down event, we put in place handlers for move and up events, and a timer.  If the
             * timer expires before we see a move or up, then we have a long press and hence a column menu open.
             * If the up happens before the timer, then we have a click, and we sort if the column is sortable.
             * If a move happens before the timer, then we are doing column move, so we do nothing, the moveable feature
             * will handle it.
             *
             * To deal with touch enabled devices that also have mice, we only create our handlers when
             * we get the down event, and we create the corresponding handlers - if we're touchstart then
             * we get touchmove and touchend, if we're mousedown then we get mousemove and mouseup.
             *
             * We also suppress the click action whilst this is happening - otherwise after the mouseup there
             * will be a click event and that can cause the column menu to close
             *

     *  @name updateColumnWidths
     *  @propertyOf  ui.grid.class:GridRenderContainer
     *  @description Determine the appropriate column width of each column across all render containers.
     *
     *  Column width is easy when each column has a specified width.  When columns are variable width (i.e.
     *  have an * or % of the viewport) then we try to calculate so that things fit in.  The problem is that
     *  we have multiple render containers, and we don't want one render container to just take the whole viewport
     *  when it doesn't need to - we want things to balance out across the render containers.
     *
     *  To do this, we use this method to calculate all the renderContainers, recognising that in a given render
     *  cycle it'll get called once per render container, so it needs to return the same values each time.
     *
     *  The constraints on this method are therefore:
     *  - must return the same value when called multiple times, to do this it needs to rely on properties of the
     *    columns, but not properties that change when this is called (so it shouldn't rely on drawnWidth)
     *
     *  The general logic of this method is:
     *  - calculate our total available width
     *  - look at all the columns across all render containers, and work out which have widths and which have
     *    constraints such as % or * or something else
     *  - for those with *, count the total number of * we see and add it onto a running total, add this column to an * array
     *  - for those with a %, allocate the % as a percentage of the viewport, having consideration of min and max
     *  - for those with manual width (in pixels) we set the drawnWidth to the specified width
     *  - we end up with an asterisks array still to process
     *  - we look at our remaining width.  If it's greater than zero, we divide it up among the asterisk columns, then process
     *    them for min and max width constraints
     *  - if it's zero or less, we set the asterisk columns to their minimum widths
     *  - we use parseInt quite a bit, as we try to make all our column widths integers

   * # ui.grid.grouping
   *
   * <div class="alert alert-warning" role="alert"><strong>Beta</strong> This feature is ready for testing, but it either hasn't seen a lot of use or has some known bugs.</div>
   *
   * This module provides grouping of rows based on the data in them, similar
   * in concept to excel grouping.  You can group multiple columns, resulting in
   * nested grouping.
   *
   * In concept this feature is similar to sorting + grid footer/aggregation, it
   * sorts the data based on the grouped columns, then creates group rows that
   * reflect a break in the data.  Each of those group rows can have aggregations for
   * the data within that group.
   *
   * This feature leverages treeBase to provide the tree functionality itself,
   * the key thing this feature does therefore is to set treeLevels on the rows
   * and insert the group headers.
   *
   * Design information:
   * -------------------
   *
   * Each column will get new menu items - group by, and aggregate by.  Group by
   * will cause this column to be sorted (if not already), and will move this column
   * to the front of the sorted columns (i.e. grouped columns take precedence over
   * sorted columns).  It will respect the sort order already set if there is one,
   * and it will allow the sorting logic to change that sort order, it just forces
   * the column to the front of the sorting.  You can group by multiple columns, the
   * logic will add this column to the sorting after any already grouped columns.
   *
   * Once a grouping is defined, grouping logic is added to the rowsProcessors.  This
   * will process the rows, identifying a break in the data value, and inserting a grouping row.
   * Grouping rows have specific attributes on them:
   *
   *  - internalRow = true: tells us that this isn't a real row, so we can ignore it
   *    from any processing that it looking at core data rows.  This is used by the core
   *    logic (or will be one day), as it's not grouping specific
   *  - groupHeader = true: tells us this is a groupHeader.  This is used by the grouping logic
   *    to know if this is a groupHeader row or not
   *
   * Since the logic is baked into the rowsProcessors, it should get triggered whenever
   * row order or filtering or anything like that is changed.  In order to avoid the row instantiation
   * time, and to preserve state across invocations, we hold a cache of the rows that we created
   * last time, and we use them again this time if we can.
   *
   * By default rows are collapsed, which means all data rows have their visible property
   * set to false, and only level 0 group rows are set to visible.
   *

   *
   * This module provides the ability to import data into the grid. It
   * uses the column defs to work out which data belongs in which column,
   * and creates entities from a configured class (typically a $resource).
   *
   * If the rowEdit feature is enabled, it also calls save on those newly
   * created objects, and then displays any errors in the imported data.
   *
   * Currently the importer imports only CSV and json files, although provision has been
   * made to process other file formats, and these can be added over time.
   *
   * For json files, the properties within each object in the json must match the column names
   * (to put it another way, the importer doesn't process the json, it just copies the objects
   * within the json into a new instance of the specified object type)
   *
   * For CSV import, the default column identification relies on each column in the
   * header row matching a column.name or column.displayName. Optionally, a column identification
   * callback can be used.  This allows matching using other attributes, which is particularly
   * useful if your application has internationalised column headings (i.e. the headings that
   * the user sees don't match the column names).
   *
   * The importer makes use of the grid menu as the UI for requesting an
   * import.

   *  @description Stacks on top of ui.grid.uiGridHeaderCell to provide capability to be able to move it to reposition column.
   *
   *  On receiving mouseDown event headerCell is cloned, now as the mouse moves the cloned header cell also moved in the grid.
   *  In case the moving cloned header cell reaches the left or right extreme of grid, grid scrolling is triggered (if horizontal scroll exists).
   *  On mouseUp event column is repositioned at position where mouse is released and cloned header cell is removed.
   *
   *  Events that invoke cloning of header cell:
   *    - mousedown
   *
   *  Events that invoke movement of cloned header cell:
   *    - mousemove
   *
   *  Events that invoke repositioning of column:
   *    - mouseup

   * @ngdoc overview
   * @name ui.grid.treeBase
   * @description
   *
   * # ui.grid.treeBase
   *
   * <div class="alert alert-warning" role="alert"><strong>Beta</strong> This feature is ready for testing, but it either hasn't seen a lot of use or has some known bugs.</div>
   *
   * This module provides base tree handling functions that are shared by other features, notably grouping
   * and treeView.  It provides a tree view of the data, with nodes in that
   * tree and leaves.
   *
   * Design information:
   * -------------------
   *
   * The raw data that is provided must come with a $$treeLevel on any non-leaf node.  Grouping will create
   * these on all the group header rows, treeView will expect these to be set in the raw data by the user.
   * TreeBase will run a rowsProcessor that:
   *  - builds `treeBase.tree` out of the provided rows
   *  - permits a recursive sort of the tree
   *  - maintains the expand/collapse state of each node
   *  - provides the expand/collapse all button and the expand/collapse buttons
   *  - maintains the count of children for each node
   *
   * Each row is updated with a link to the tree node that represents it.  Refer {@link ui.grid.treeBase.grid:treeBase.tree tree documentation}
   * for information.
   *
   *  TreeBase adds information to the rows
   *  - treeLevel: if present and > -1 tells us the level (level 0 is the top level)
   *  - treeNode: pointer to the node in the grid.treeBase.tree that refers
   *    to this row, allowing us to manipulate the state
   *
   * Since the logic is baked into the rowsProcessors, it should get triggered whenever
   * row order or filtering or anything like that is changed.  We recall the expanded state
   * across invocations of the rowsProcessors by the reference to the treeNode on the individual
   * rows.  We rebuild the tree itself quite frequently, when we do this we use the saved treeNodes to
   * get the state, but we overwrite the other data in that treeNode.
   *
   * By default rows are collapsed, which means all data rows have their visible property
   * set to false, and only level 0 group rows are set to visible.
   *
   * We rely on the rowsProcessors to do the actual expanding and collapsing, so we set the flags we want into
   * grid.treeBase.tree, then call refresh.  This is because we can't easily change the visible
   * row cache without calling the processors, and once we've built the logic into the rowProcessors we may as
   * well use it all the time.
   *
   * Tree base provides sorting (on non-grouped columns).
   *
   * Sorting works in two passes.  The standard sorting is performed for any columns that are important to building
   * the tree (for example, any grouped columns).  Then after the tree is built, a recursive tree sort is performed
   * for the remaining sort columns (including the original sort) - these columns are sorted within each tree level
   * (so all the level 1 nodes are sorted, then all the level 2 nodes within each level 1 node etc).
   *
   * To achieve this we make use of the `ignoreSort` property on the sort configuration.  The parent feature (treeView or grouping)
   * must provide a rowsProcessor that runs with very low priority (typically in the 60-65 range), and that sets
   * the `ignoreSort`on any sort that it wants to run on the tree.  TreeBase will clear the ignoreSort on all sorts - so it
   * will turn on any sorts that haven't run.  It will then call a recursive sort on the tree.
   *
   * Tree base provides treeAggregation.  It checks the treeAggregation configuration on each column, and aggregates based on
   * the logic provided as it builds the tree. Footer aggregation from the uiGrid core should not be used with treeBase aggregation,
   * since it operates on all visible rows, as opposed to to leaf nodes only. Setting `showColumnFooter: true` will show the
   * treeAggregations in the column footer.  Aggregation information will be collected in the format:
   *
   * ```
   *   {
   *     type: 'count',
   *     value: 4,
   *     label: 'count: ',
   *     rendered: 'count: 4'
   *   }
   * ```
   *
   * A callback is provided to format the value once it is finalised (aka a valueFilter).
   *

   *
   * Validation is not based on angularjs validation, since it would work only when editing the field.
   * 
   * Instead it adds custom properties to any field considered as invalid.

     * Component resolution and creation flow:
     *
     * Because directives are not containing each other in their templates (e.g. not a general parent-child
     * relationship), that's why the resolution of different components are not obvious. They are working with
     * transclusion and it's rule will apply to the process flow.
     * Here is an overview on what directives and which part of that will execute in which order.
     *
     * 1. `mdtTable` controller
     *         - basic services initialized for future usage by other directives
     *
     * 2. `mdtTable` link
     *         - transclude `mdtHeaderRow` and all `mdtRow` elements generated contents (however it's not relevant,
     *           the real generated content is generated with the help of the collected data by `TableStorageService`.
     *         - bind some helper functions for real the generated content
     *
     * 3. Header resolution
     *
     *     3.1. `mdtHeaderRow` link
     *              - transclude all `mdtColumn` directive's generated contents
     *
     *     3.2. `mdtColumn` link(s)
     *              - add columns by the help of the `mdtTable` public API
     *              - contents generated but not yet transcluded
     *
     * 4. Rows resolution
     *
     *     4.1. `mdtRow` controller(s)
     *              - public function created which able to add a cell data to the locally stored array
     *
     *     4.2. `mdtRow` link(s)
     *              - transclude all `mdtCell` directive's generated  contents
     *              - add the collected row data to the service by the help of `mdtTable` public API
     *
     *     4.3. `mdtCell` link(s)
     *              - add cells data by the help of `mdtRow` public API
     *              - contents generated but not yet transcluded

     * @restrict E
     *
     * @description
     * The base HTML tag for the component.
     *
     * @param {object=} tableCard when set table will be embedded within a card, with data manipulation tools available
     *      at the top and bottom.
     *
     *      Properties:
     *
     *      - `{boolean=}` `visible` - enable/disable table card explicitly
     *      - `{string}` `title` - the title of the card
     *      - `{boolean=}` `columnSelector` - enables the column selection for the table (you can disable certain columns from the list selection, using `exclude-from-column-selector`, see the related docs)
     *      - `{array=}` `actionIcons` - (not implemented yet)
     *
     * @param {boolean=} selectableRows when set each row will have a checkbox
     * @param {boolean=} virtualRepeat when set, virtual scrolling will be applied to the table. You must set a fixed
     *      height to the `.md-virtual-repeat-container` class in order to make it work properly. Since virtual
     *      scrolling is working with fixed height.
     * @param {String=} alternateHeaders some table cards may require headers with actions instead of titles.
     *      Two possible approaches to this are to display persistent actions, or a contextual header that activates
     *      when items are selected
     *
     *      Assignable values are:
     *
     *      - 'contextual' - when set table will have kind of dynamic header. E.g.: When selecting rows, the header will
     *        change and it'll show the number of selected rows and a delete icon on the right.
     *      - 'persistentActions' - (not implemented yet)
     *
     * @param {function(rows)=} deleteRowCallback callback function when deleting rows.
     *      At default an array of the deleted row's data will be passed as the argument.
     *      When `table-row-id` set for the deleted row then that value will be passed.
     *
     * @param {function(rows)=} selectedRowCallback callback function when selecting rows.
     *      At default an array of the selected row's data will be passed as the argument.
     *      When `table-row-id` set for the selected row then that value will be passed.
     *
     * @param {boolean=} animateSortIcon sort icon will be animated on change
     * @param {boolean=} rippleEffect ripple effect will be applied on the columns when clicked (not implemented yet)
     * @param {boolean=} paginatedRows if set then basic pagination will applied to the bottom of the table.
     *
     *      Properties:
     *
     *      - `{boolean=}` `isEnabled` - enables pagination
     *      - `{array}` `rowsPerPageValues` - set page sizes. Example: [5,10,20]
     *
     * @param {object=} mdtRow passing rows data through this attribute will initialize the table with data. Additional
     *      benefit instead of using `mdt-row` element directive is that it makes possible to listen on data changes.
     *
     *      Properties:
     *
     *      - `{array}` `data` - the input data for rows
     *      - `{integer|string=}` `table-row-id-key` - the uniq identifier for a row
     *      - `{function(rowData)=}` `table-row-class-name` - callback to specify the class name of a row
     *      - `{array}` `column-keys` - specifying property names for the passed data array. Makes it possible to
     *        configure which property assigned to which column in the table. The list should provided at the same order
     *        as it was specified inside `mdt-header-row` element directive.
     *
     * @param {function(page, pageSize, options)=} mdtRowPaginator providing the data for the table by a function. Should set a
     *      function which returns a promise when it's called. When the function is called, these parameters will be
     *      passed: `page` and `pageSize` which can help implementing an ajax-based paging, and `options` which is providing
     *      more information.
     *
     *      Currently these are available from options:
     *      - `array` `columnFilter` - an array of the filtered column sets (todo: create a demo for it)
     *      - `array` `columnSort` - an array of the sorted column sets. You can inspect which column did you
     *                               sorted and if its in asc or desc order (todo: create a demo for it)
     *
     * @param {string=} mdtRowPaginatorErrorMessage overrides default error message when promise gets rejected by the
     *      paginator function.
     *
     * @param {string=} mdtRowPaginatorNoResultsMessage overrides default 'no results' message.
     *
     * @param {function(loadPageCallback)=} mdtTriggerRequest provide a callback function for manually triggering an
     *      ajax request. Can be useful when you want to populate the results in the table manually. (e.g.: having a
     *      search field in your page which then can trigger a new request in the table to show the results based on
     *      that filter.
     *
     * @param {object=} mdtTranslations accepts various key-value pairs for custom translations.
     *
     * @param {boolean=} mdtLoadingIndicator if set then loading indicator can be customised
     *
     *      Properties:
     *
     *      - `{string=}` `color` - passing a css compatible format as a color will set the color for the loading indicator
     *
     * @example
     * <h2>`mdt-row` attribute:</h2>
     *
     * When column names are: `Product name`, `Creator`, `Last Update`
     * The passed data row's structure: `id`, `item_name`, `update_date`, `created_by`
     *
     * Then the following setup will parse the data to the right columns:
     * <pre>
     *     <mdt-table
     *         mdt-row="{
     *             'data': controller.data,
     *             'table-row-id-key': 'id',
     *             'column-keys': ['item_name', 'update_date', 'created_by']
     *         }">
     *
     *         <mdt-header-row>
     *             <mdt-column>Product name</mdt-column>
     *             <mdt-column>Creator</mdt-column>
     *             <mdt-column>Last Update</mdt-column>
     *         </mdt-header-row>
     *     </mdt-table>
     * </pre>
