Refactored database storage system and retrieval process.

TODO:
  * build filter for individual classrooms page
updated script tags
updated classroom controller to test for filters
added new fb controller file
Added routing for single classroom

NOTE:
 * routing does not update on JUST route url change.. currently requires page refresh. this will work fine when a user enters a room, but may cause issues when they try to change rooms from within the app..
updated routing to allow for page changes without refreshing..

TO FIX:
* when you refresh page, whole data set loads..
