//! This class describes a MultiBSpCurve approximating a Multiline.
//! Just as a Multiline is a set of a given number of lines, a MultiBSpCurve is a set
//! of a specified number of bsplines defined by:
//! - A specified number of MultiPoints - the poles of a specified number of curves
//! - The degree of approximation identical for each of the specified number of curves.
//!
//! Example of a MultiBSpCurve composed of a specified number of MultiPoints:
//!
//! P1______P2_____P3______P4________........_____PNbMPoints
//!
//! Q1______Q2_____Q3______Q4________........_____QNbMPoints
//! . .
//! . .
//! . .
//! R1______R2_____R3______R4________........_____RNbMPoints
//!
//! Pi, Qi, ..., Ri are points of dimension 2 or 3.
//!
//! (Pi, Qi, ...Ri), i= 1,...NbPoles are MultiPoints.
//! each MultiPoint has got NbPol Poles.
//! MultiBSpCurves are created by the SplineValue method in the ComputeLine
//! class, and by the Value method in TheVariational class. MultiBSpCurve
//! provides the information required to create the BSpline defined by the approximation.
