Comment:
I put a needs work because we must set on sage-combinat-devel if we plan
to refactor integer vector as hashable type...
I mainly implement this object to create an algebra whose basis is indexed
by orbit_sum of monomial. But CombinatorialFreeModule requires hashable
elements as basis keys. There is a choice here and I don't have the
language overview to decide such direction.
