class  Convert_EllipseToBSplineCurve
 This algorithm converts a ellipse into a rational B-spline curve.
The ellipse is represented an Elips2d from package gp with
the parametrization :
P (U) =
Loc + (MajorRadius * Cos(U) * Xdir + MinorRadius * Sin(U) * Ydir)
where Loc is the center of the ellipse, Xdir and Ydir are the
normalized directions of the local cartesian coordinate system of
the ellipse. The parametrization range is U [0, 2PI].
KeyWords :
Convert, Ellipse, BSplineCurve, 2D .
