Comment:
Generators of homology now computable via generators=true option in the
homology() method of chain_complex.
Known issues: If S is a simplicial complex, S.homology(generators=true)
has not been directly implemented. Furthermore,
S.chain_complex().homology(generators=true) computes the generators based
on the order in which simplices are chosen for computing S.chain_complex()
-- which is not guaranteed to be the same order in which simplices are
listed in S.
