I have attached a patch that adds a gr_mean_XX block to gnuradio-core.
The block calculates the arithmetic mean of a single vector. The
variance block should be quite easy to create using this one as a
template. I have not added the various bits and pieces to Makefile.am
etc, but that should (in theory... :) ) not be too hard.

Cheers,
