added droc-on-subsets.R for plotting sl1 and sl2 values for different cut-off iteration points. Also some clean-up of R project files.
Added droc.foriterations - same as plot.droc.foriterations, but returns result instead of plotting. Also added droc.foriterations.unaveraged, which calculates drocs for each sample instead of average of all samples.
Created report for this leg of the research
