Made mwu.consecutivePairs.at(...) to return a matrix with 1 column containing the mwu results for each pair of inputs, where the rows are named for the rows of the input being compared. Also added a text file with some results of using this function to test levels of change in diversity on gbest.
removed unused functions in ranks.R
moved the only method from ranks.R that I use, called rankF(...), to mwu-methods.R, and removed the file.
removed some unused files
