Version 1.1 -- Updated code to use S4 object "mirnapath" instead of S3 object. -- Changes "Enriched by Gene" and "Enriched by miRNA" not to be a concatenated long string -- almost always too long to read anyway. Version 1.0 Initial release. Version 1.1 Changed objects to S4 format Version 1.1.1 Updated runEnrichment and mirnaTable to remove the "Enriched by miRNA" concatenated strings, which were way too long to be useful. Version 1.1.3 Updated the miRNA-gene counts methodology; fixed the strategy for ignoring pathways with no hits. Version 1.3.3 Updated permutation logic to handle empty when permutations show enrichment in only a subset of overall pathways.
