generic class SurfFunction from Contap
(TheSurface as any;

inherits FunctionSetWithDerivatives from math
---Purpose: This class describes the function on a parametric surface.
-- the form of the function is F(u,v) = 0 where u and v are
-- the parameteric coordinates of a point on the surface,
-- to compute the contours of the surface.
