[Numpy-discussion] How to call import_array() properly?

The module I'm working with, which uses Boost, doesn't have a function
"initcvisual". Rather there's a section headed with
BOOST_PYTHON_MODULE( cvisual). Placing the import_array macro directly
in this section causes an unwanted return.
I guess it doesn't matter, since what I've done works okay. And I
realized that I could collapse init_numpy a bit:
#if PY_MAJOR_VERSION >= 3
