refactored the streetsmart mocked data and added gis information to it.
removed mock data from the app that wasn't contributed by christina (hope to speed up the application)
added geo-location distance algorithms to the app, they aren't integrated into angular, though.
seperated christina's mls listing from the rest of the mock data. we can add more listings to this structure.
added assoc_in function to underscore.js
changed the default mls listing id to to match the only listing that is currently mocked out.
removed refs to previous project's mocked out http calls
made the data fetching for the mls listing a 2 step process.
-fetch mls listing
-fetch surrounding places based off of mls gis data

included mocks for the new step and made it so the returned data is filtered on gis proximity
added address directive
refactored the 'display' partial so that it shows the distance of each place relative to the mls location.
sorted on distance
included a mls view as well (it was empty before)
