Comment(by novoselt):
One more global question: did you think about having most of the
functionality in `ChowGroup_degree_class` with Chow cycles being tuples of
elements from all of them, i.e. without having the total quotient module?
That would take care of some of the issues above (like gens vs.
gens(degree=k)) and would avoid `flatten(fan.cones())` which I don't
really like. It would also make sense to let fans determine indices of the
cones in the lists in this case, i.e. `fan._index_of(cone)` would return
the index of cone in `fan.cones(dim=cone.dim())`.
