Comment:

 I've made a few small changes:

 - added some doctests explicitly involving the mod 2 generic Steenrod
 algebra. I guess this is mostly not necessary, since the generic code gets
 tested well at odd primes, but I added these anyway.

 - top of the file: added `# -*- coding: utf-8 -*-` so the accent in
 "Études" wouldn't break docbuilding.

 - fixed a pre-existing bug in `_latex_term` for the "pst" basis

 - changed the `__contains__` method so that elements in the ordinary mod 2
 Steenrod algebra are not contained in the generic version. Is this the
 right thing to do?

 If you're happy with these changes, it can get a positive review.
