Detailed Description

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.
