Comment (by jhpalmieri):

 Here are a few small changes which I think are self-explanatory. A
 request: in the `homology` method, you have
 {{{
         try:
             return C.homology(d)
         except NotImplementedError:
             pass
         ...
 }}}
 Could you add a doctest that tests the second part of this: an example in
 which a `NotImplementedError` is raised? I added a print statement after
 the `try ... except` block, and it never executed.
