Contruct and add a new edge of the given kind and connect the given ports.

Parameters:

fromPort - The originating port to connect

toPort - The destination port to connect

edgeClass - The NSUML type of edge to create.

Returns:

The type of edge created (the same as edgeClass if we succeeded, null otherwise)
