starting work on importing gsea results
renamed gsea results files for ease of use
gmt file importer
this version gives an error when trying to pass the graph to Cytoscape. Seems to be a problem with the XML
using a new ID that does not have funny characters so we don't end up with NA nodes
runs and spits out results to cytoscape
added a bunch of commentary on what is being done and why.
moved readGMT and readGSEAResults functions to be actual functions in the categoryCompare namespace.
Merge branch 'paper' of https://github.com/rmflight/categoryCompare into paper
