Detailed Description

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.
