Multi-taper spectral analysis code available

[martin smith]

This is the initial release of a module that implements Thomson's
multi-taper spectral analysis algorithms.  The code is based on a
subroutine from Lees and Park and has, of course, a python interface.
References are provided in the readme file.  It requires that numpy be
available.

The code has seen substantial usage and should be fairly reliable.
Examples are included.

It's available at http://code.google.com/p/pymutt/.
