Title: fix #14: automatic cythonization if cython present

Hi Pierre,

As promised, here is a PR that implements the behaviour I expected:
- support for cythonization is detected automatically
- if cython is detected, use a fresh cythonization to build the extension
- necessary to add a "force" option, otherwise cythonize will still be using the old c-files
