 * The numpy API is a C api where pointers to functions and objects are the
 * same size.
 * This is not guaranteed by the C++ standard so macros in the numpy headers,
 * such as PyArray_IterNew produces warnings when compiled with a C++ compiler.
 *
 * The only solution appears to be wrap the calls in our own functions and
 * suppress the warnings.
