First version of caching street view images. Major bugs: 1)  Unoptimized, saves images everytime popup is closed, causes big performance issues and 2) if internet goes down, app must be stopped and restarted for cached images to appear
First phase complete: Sync buildings from Eddie end
Phase 3: Locally storing street view images as building properties to not require internet access
Phase 2: Globalized building manager to app delegate, points to both table view controller and detail view controller
resolved merge conflicts for building syncing changes
