numerix and numpy

Before we blow away the numerix internally, let's give this release a
few days to settle and do a point bug fix release if anything serious
comes out. I plan on doing an announcement on python-list tomorrow,
which should trigger a larger than normal number of downloads, so
let's give it a couple of days to shake out before we pull numerix.

Of course we can always branch, but I'd be happy to keep it simple.
