Update.
Bugfix changing fft to fft2 in beamform_thumb (thanks to D.Jacobs for catching!)
Committing various pspec_redmult_cov flavors.
Update to pspec_redmult_cov.py.  I think the noise normalization is basically correct.  Major improvement in removal of systematics.
Working version of pspec_redmult_cov.py that does a good job.
Restructure of pspec_redmult_cov.py for clarity/cleanup.
Trying to reincorporate Fisher matrix stuff back into pspec_redmult_cov.  Currently wrong b/c the matrix for projecting out systematics is being treated as the inverse covariance matrix, which it is not.
More mature versoion of pspec_redmult_cov.py, although pretty sure at this point that it introduces a noise bias.
