class MultiPoint from AppParCurves
    	---Purpose: This class describes Points composing a MultiPoint.
    	--          These points can be 2D or 3D. The user must first give the 
    	--          3D Points and then the 2D Points.
   	--          They are Poles of a Bezier Curve.
    	-- This class is used either to define data input or
    	-- results when performing the approximation of several lines in parallel.

    Create(NbPoints, NbPoints2d: Integer)
    	---Purpose: constructs a set of Points used to approximate a
