Sorts the edge list for the mesh topology vertex list so that
the edges are in radial order when you call ConnectedTopologyVertices.
A non-manifold edge is treated as a boundary edge with respect
to sorting. If any boundary or non-manifold edges end at the
vertex, then the first edge will be a boundary or non-manifold edge.
