added gseaProportion function. Unfortunately, this won't work, because we need the indeces to remain the same, and the value of the statistic to move, ie. to change the rank between samples.
first crack at independent terms using the same indices. Not exactly promising
got things finally working, in gseaProportion, but list still gives better results
trying to force it by making up anywhere from 1:7500, and down only the last 2500
added a new function for having different significant proportions different between the two samples
back to using 50% as cutoff, and checking that the gseaProportion function does what we think
using variable proportions between samples
check that this will work with transformed from p-value to signed data
added comment about final things to try before doing current method
