Quoting James: An alternative would be to simply delete cutils_ext as cruft, and
create proper callable Types in the auto-generated C files. It's not
hard to do that, but it takes some familiarity with the Python C API.
That is a cleaner solution, and makes nice progress towards being able
to use Theano compiled modules on their own...
