Edges for `SimpleGraph` still consider their directedness when testing for equality and hashing. This is understandable given that `SimpleEdge` is used for directed graphs also. Is it worth considerin…

We should provide an undirected graph abstraction. At the moment the csr graph is directed.
For use what we have and turn it into an undirected graph, we'll need
