Work_issues: add detailed comments to cohomology related methods |
-------------------------------------------------------------------+--------
Comment(by vbraun):
Here is my final patch :-)
* Polyhedron can now determine integral points in not necessarily
integral polytopes.
* Used this to extend cohomology computation to reflexive sheaves.
* Renamed `ToricDivisor.polytope()` to `polyhedron()` since its not a
lattice polytope in general.
* Documentation added to cohomology algorithm.
* Output of `ToricDivisor.cohomology()` is now analogous to the output
of `SimplicialComplex.homology()`
* renamed `ToricVariety.divisor_class_group()` to
`rational_class_group()`
