now produce Canudas Romo decomp for both males and females, but need to
see if I accidentally swapped something
added weighted mean wmean() and variance wvar()- used for the
Remund-Romo tests
working on at least getting the 2d pdf to be intermediate. slight
success. need to refine to work on local pdfs, possibly scaled...

so far only doing stolarsky means, which is order independent- really
should jump to simple weighted means to consistently differentiate
sexes. Stolarsky is consistent with monotonicity, which i dispute anyway
added weighted avg of two matrices
adding more sophisticated means- i.e. sex-specific weights, rather than
larger/smaller means. Stolarsky can't know which sex is which. also
upper vs lower tri, 3x3 blocks
.
writing at close of day feb 5th, 2013. looks like 3-4 pages of
