If this is nicely-licensed C code that provides a superset of
scipy.fftpack's functionality, ought we to merge it into *numpy*.fft
and deprecate scipy.fftpack? (I'm a little confused at what exactly
the difference between the numpy and scipy modules is in this case,
except that of course the scipy version needs a fortran compiler.)
