I've checked it in.

Highlights:

* You only need to edit customize.py

* You don't need to edit if you're on OS X (>= 10.2): the vecLib
  framework for optimized BLAS and LAPACK will be used if found.

* If you have an incomplete ATLAS library (one without LAPACK), you
  can use it for BLAS (instead of blas_lite.c), and the included f2c'd
  routines for LAPACK will be used.

* Use whatever CBLAS interface you've got (ATLAS, GSL, the reference
  one available from netlib).

There's also an INSTALL file now, although it could some comments
about the 'python setup.py config' option.
