    ---Purpose: compute position of VPoint <VP> regarding with face <F>.
    -- <ShapeIndex> (= 1,2) indicates which (u,v) point of <VP> is used.
    -- when state is ON, set VP.EdgeON() with the edge containing <VP>
    -- and associated parameter.
    -- returns state of VP on ShapeIndex.
    returns State from TopAbs is static;
        
    Edge(me) 
    ---Purpose: returns the edge containing the VPoint <VP> used in the
    -- last VPointPosition() call. Edge is defined if the state previously 
    -- computed is ON, else Edge is a null shape.
    ---C++: return const &
    returns Shape from TopoDS is static;
    	
    EdgeParameter(me) 
    ---Purpose: returns the parameter of the VPoint <VP> on Edge()
    returns Real from Standard is static;
