Merge pull request #3 from dvincent/master

Consider dv's code from Friday morning.
Start of PPRClientManager.
Merge remote-tracking branch 'pegwing/master'
Added filtering on “Facility” to client manager and “Facility Id” column to clients and facility id column to facilities.
Added FacilityManager and refactored ShiftViewController to used FacilityManager
Setting Facility in the Shift View asserts a user default with the Id of the current facility and uses NSNotificationCenter to schedule a tableview reloadData in the ClientTableViewController.
ClientTableViewController now filters the client list on the current selected facility and registers for changes to the currently selected facility via NSNotificationCenter.
Add navigation and shift.
