 A topology.Polygonize function might be an excellent companion of AddEdge
 in that it would greatly simplify batch topology construction (ie: when
 you already have a set of noded edges).

 Basically you would:
  1. topology.AddEdge for each edge
  2. topology.Polygonize when done

 By that time, you'd have nodes, edges and faces all in place.
