//! Describes a MultiPointConstraint used in a <br>
//! Multiline. MultiPointConstraints are composed <br>
//! of several two or three-dimensional points. <br>
//! The purpose is to define the corresponding <br>
//! points that share a common constraint in order <br>
//! to compute the approximation of several lines in parallel. <br>
//! Notes: <br>
//! -   The order of points of a MultiPointConstraints is very important. <br>
//!   Users must give 3D points first, and then 2D points. <br>
//! -   The constraints for the points included in a <br>
//!   MultiPointConstraint are always identical for <br>
//!   all points, including the parameter. <br>
//! -   If a MultiPointConstraint is a "tangency" <br>
//!   point, the point is also a "passing" point. <br>
