Testing brach pull request

Have moved functions from json_to_db into xalt_rmap_util and xalt_util.  Also made new functions now found in XALTdb2 from code in json_to_db and significantly shorted json_to_db.  

Modified xalt_transmission_factory to support direct to db method, but I have two hardcoded paths in it -- that needs to be fixed.

and one small fix to the xalt_site_pkg.py file.
