I notice that out_degree is a requirement for IncidenceGraph, one of the
most-basic useful graph concepts, but that it's only used in isomorphism()
and minimum_degree_ordering(). Since finding the out_degree can be a burden
for heuristic searches of spaces which aren't represented in memory, I think
this restriction should be lifted in most places, e.g. for
breadth_first_visit().
