//! The array NbPoints contains the number of points for each constraint.
//! The Array Tang contains the order of constraint for each Constraint: The possible values for this
//! order has to be -1 , 0 , 1 , 2 . Order i means constraint Gi.
//! NbIter is the maximum number of iteration to optimise the number of points for resolution
//! Degree is the degree of resolution for Plate
//! Tol2d is the tolerance used to test if two points of different constraint are identical in the

//! Tol3d is used to test if two identical points in the 2d space are identical in 3d space
//! TolAng is used to compare the angle between normal of two identical points in the 2d space

//! Initializes the BuildPlateSurface framework for
//! deforming plate surfaces using curve and point
//! constraints. You use the first constructor if you have
//! an initial surface to work with at construction time. If
//! not, you use the second. You can add one later by
//! using the method LoadInitSurface. If no initial
//! surface is loaded, one will automatically be computed.
//! The curve and point constraints will be defined by
//! using the method Add.
//! Before the call to the algorithm, the curve constraints
//! will be transformed into sequences of discrete points.
//! Each curve defined as a constraint will be given the
//! value of NbPtsOnCur as the average number of points on it.
//! Several arguments serve to improve performance of
//! the algorithm. NbIter, for example, expresses the
//! number of iterations allowed and is used to control the
//! duration of computation. To optimize resolution,
//! Degree will have the default value of 3.
//! The surface generated must respect several tolerance values:
//! - 2d tolerance given by Tol2d, with a default value of 0.00001
//! - 3d tolerance expressed by Tol3d, with a default value of 0.0001
//! - angular tolerance given by TolAng, with a default
//! value of 0.01, defining the greatest angle allowed
//! between the constraint and the target surface.
