deferred generic class PSurfaceTool from IntStart
    (ThePSurface as any)
                                   

	---Purpose: Template class for a tool on a bi-parametrised
	--          surface.
	--          It is possible to implement this class with an 
	--          instantiation of the SurfaceTool from Adaptor3d.
