Replying to [comment:25 vbraun]:
A3. OK, let's hope it will get fixed eventually...
A6. Am I right that it is integral OF the dual cohomology class, not OVER?
That's how I interpret `integrate` method of toric varieties. Also it
seems that we need completeness in addition to smoothness.
A7. Let it be fixed elsewhere!
B9. Ok, let it be as is.
Fresh comments:
1. Why `get_degree` and not just `degree` for Chow cycles?
1. What will `cohomology_class` of a Chow cycle produce in the case when
there is no Poincare duality? I think this should be either explained in
the documentation, or an exception should be raised varieties which are
not smooth and complete.
I have done some documentation prettification, feel free to fold it into
your patch, if is still applies to your current version.
