Temporary branch to pass changes to work from home.
#268 Working on ontology mappign overview for new API conversion, since I am most familiar there. Cleaning out old system since it is defunct. See alert boxes and commit efforts for where to pick up from.
#268 Set up ontology overview graph to use the new API. Also tried to excise virtual ontology id and ontology id variables and concepts. Much to be done in all remaining visualizations, REST callers, and parsers.
#268 Have more work done for term neighborhood, some done for mappings neighborhood and path to root. Looking into bug where sometimes arcs don't show up for the term neighborhood. Also, the has_a relations are not available in the new API apparently, so they do not manifest.
