Comment(by vbraun):
About the `divisor_group_*` methods, I agree with your argument but I also
hate to give the longer name to the most useful method. And I don't want
to introduce a unified parent for divisors, the current inheritance tree
fits OOP as well as mathematics nicely. So I propose the following, we'll
have only one `divisor_group` method
{{{
def divisor_group(divisors='T-Weil', base_ring=ZZ):
}}}
That'll easily generalize to any other notion of divisor that one might
want to introduce and, by default, returns the most useful case for toric
varieties.
