Merge pull request #15 from collinatherton/master

Added MKMapItem container/linked-list class WalkMapItem
Notification improvements.
1. Implemented the Constants for Notification.
2. Made AppDelegate a bit cleaner, started to add code to work with Notification related region monitoring. I need the regions, Uber related code and such before I can add the stuff.
3. Finished the notification actions and the setup for them.
