Mpl does not depend on scipy at all and it is intended to stay that way.
Mind you, mpl does not "require" acorr/xcorr because we do it using
existing numpy tools. And any user needing a faster version can simply call
it themselves and simply plot the results themselves. The current
functions are merely convenience functions
So, yes, it would be nice to have it in numpy, but if it fits better in
scipy, then put it there.
