class InteriorPoint from IntSurf

	---Purpose: Definition of a point solution of the
	--          intersection between an implicit an a
	--          parametrised surface. These points are
	--          passing points on the intersection lines,
	--          or starting points for the closed lines
	--          on the parametrised surface.
