class MultiCurve from AppParCurves
---Purpose: This class describes a MultiCurve approximating a Multiline.
-- As a Multiline is a set of n lines, a MultiCurve is a set
-- of n curves. These curves are Bezier curves.
-- A MultiCurve is composed of m MultiPoint.
-- The approximating degree of these n curves is the same for
-- each one.
--
--
-- Example of a MultiCurve composed 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.
