0032146: Modeling Data - Add Ellipsoid Surface Support
Ellipsoid parametric equation is similar to sphere:
x = a cos(u) sin(v)
y = b sin(u) sin(v)
z = c cos(v)

Now the modeling for Ellipsoid in opencascade is:
1 Make a sphere
2 Use BRepBuilderAPI_GTransform to scale the sphere, and the result is BSpline Surface.

Like Geom_SphericalSurface add a class Geom_EllipsoidSurface for Ellipsoid as elementary surface directly.
