#3 simple psyco math module

[Khalid Zuberi]

Here's a cut at a psyco-ized version of python's
mathmodule.c. Implementation borrows from the work
in pfloatobject.c.

Its not complete, needing a couple more functions
added, as well as proper handling for eg domain
errors etc (which I expect will slow it down a bit).

It seems to compile and work on my linux box. Not
tested on windows.
