Comment(by vbraun):
3. I think we should only introduce a `cohomology_dim` if there is already
a `cohomology` method, and there isn't. The difference with simplicial
complexes is, of course, that their cohomology (over `ZZ`) potentially
contains torsion and, therefore, cannot be specified by just an integer.
8. The toric Chow group (the subsequent patch) contains the integral
class group, so the functionality is already there. The raison d'etre of
`ToricRationalDivisorClass` is to provide a parent for Kahler cones.
