generic class IntCurveCurveGen from IntCurve (
    TheCurve         as any;
    TheCurveTool     as any) -- as CurveTool from IntCurve(TheCurve)

	---Purpose: Provides the algorithm to intersect two 2D-curves.
	--          The curves may be parametric curves or Conic (see
	--          the template class CurveTool).
	--
	-- Note: The  exception  ConstructionError  is   raised  in
	--          constructors  or in Perform  methods when a domain
	--          (Domain from IntRes2d)  is not  correct, i-e  when
	--          the method  TheType  returns GeomAbs_Circle     or
	--          GeomAbs_Ellipsei   and the corresponding domain is
	--          not  closed (use the SetEquivalentParameters for a
	--          domain on  a circle  or an  ellipse)  or  when the
	--          method  TheType   returns  GeomAbs_Other and   the
	--          domain     of  the   curve   is    not     bounded
	--          (HasFirstPoint() && HasLastPoint() return True).
