generic class ToolPolygon from IntCurve (Point as any; 
    	    				 Polygon as any;
    	    	    	    	    	 BoundingBox as any)

	---Purpose: Describe a polyline  as  a topology to compute the
	--          interference beetween two polylines.


        ---Level: Internal

    ---Purpose: Give the bounding box of the polygon.
