Comment (by jaanos):
> a part of interface issue is that we lack `(di)graphs.CayleyGraph()`; if
it was there it would be most natural to return such a thing on success.
So you're saying that we should return an isomorphic graph that is marked
as a Cayley graph as a certificate? Interesting, although this is probably
something the user should do by themselves given the group.
Even if we don't have such a constructor, we can always relabel the
vertices with group elements, and then set edge labels, just like the
`cayley_graph` method on a group would do.
