[OT] pass a C callback function to a cythom module via python

[Stéfan van der Walt]

Hi Nadav

I just had a chat with Dag, a core Cython contributor.  He mentioned
to me another alternative, which is to encapsulate the callback
function in a class:

https://github.com/dagss/cython-pydata12/blob/master/examples/oointegrate/integrate.pyx

You can import this class from Python, and pass it along as the
callback object.  There may be some work on improving this
functionality in the future, but for now I think that's the cleanest
route (and helps us to avoid ctypes!).
