[Numpy-discussion] Complete and build the example from the "Using Numpy C-API" documentation.

I would like to take the example shown here: http://docs.scipy.org/doc/numpy/user/c-info.how-to-extend.html#example and complete the code so I can build and test the extension module. Is that example currently correct? It is slightly different from the older example in the numpy book, so someone must have had a reason to change it. I've added the C array of PyMethodDefs and the module init function, but I'm still searching for the correct #includes for the numpy stuff. Any suggestions (or pointers to similar simple but complete examples) would be appreciated. Warren
