class MakePolygon from BRepLib inherits MakeShape from BRepLib
---Purpose: Class to build polygonal wires.
--
-- A polygonal wire may be build from
--
-- - 2,4,3 points.
--
-- - 2,3,4 vertices.
--
-- - any number of points.
--
-- - any number of vertices.
--
--
-- When a point or vertex is added to the polygon if
-- it is identic to the previous point no edge is
-- built. The method added can be used to test it.
