fixed bug with EM made with two distinct datasets.  (It was computing edges for dataset1 when they were only enriched in dataset1)
fixed issue with two distinict dataset calculating edges for dataset1 instead of dataset2.  Fixed issue when file field is empty. Fixed issue with geneset size being set to original gene set size and not the post dataset filtered size.
fixed resizing on heatmap expression value legend.  changed show values to checkbox and moved it into the same frame as normalization.  When show values are selected make the column widths larger.
