Removed unused import
Added helper objects to use to output to the soy rather than using maps.  This is more readable I think.  Also implemented a parser for the json produced by the content translation code (in rutherford-content) in preparation for getting rid of the immutablemaps in RutherfordController
Removed the ImmutableMaps from RutherfordController and replaced them with information generated from the content files.  This has also restructured the output to soy in various ways.  New soy template files have been created for the various different pages which were getting all rolled together in a single file
Merge branch 'master' of github.com:daviesian/rutherford-server
