class  Convert_ParabolaToBSplineCurve
 This algorithm converts a parabola into a non rational B-spline curve. The parabola is a Parab2d from package gp with the parametrization P (U) = Loc + F * (U*U * Xdir + 2 * U * Ydir) where Loc is the apex of the parabola, Xdir is the normalized direction of the symmetry axis of the parabola, Ydir is the normalized direction of the directrix and F is the focal length.
