Polygon:
---------------------------------------------------------------------------
Generate the properties for a polygon given vertices in the form v(3,n).
It assumes that the polygon is planar. It computes an average normal
at all vertices.
---------------------------------------------------------------------------
Form:
[area, n, r] = Polygon( v )
