Using new services again. POI displays update_url when tapped.
HE’S ON FIRE!!!!!!!!!!!!!!!!
Started working on POI table views (for dining halls)
POI objects now have `tags` property. Stored as NSSet
New `Constants.h` file. Tapping on POI now uses multithreading to load detail view, so POI icons don’t freeze while we use the network.
Merge remote-tracking branch 'origin/master'
no more errors
Added a last-updated icon for easier debugging
XML parsing now working correctly
Renamed things and added OptionsView and OptionsViewController
