class Interpolate from GeomLib
---Purpose: this class is used to construct a BSpline curve by
-- interpolation of points at given parameters The
-- continuity of the curve is degree - 1 and the
-- method used when boundary condition are not given
-- is to use odd degrees and null the derivatives on
-- both sides from degree -1 down to (degree+1) / 2
-- When even degree is given the returned curve is of
-- degree - 1 so that the degree of the curve is odd
