in your "init" function, you need to make a call to "import_array()".
import_array is actually a 'magic macro' that does a sort of "runtime
linking" in python. if you do not make this call, all the C functions from
Numeric will only be NULL (and hence a crash)
no need for the PyImpoert_ImportModule()
