Checking for Regional Monitoring Capability

The Core Location location manager has a class method that indicates whether regional monitoring is available for the device. This can be used to customize whether an app performs regional monitoring tasks. For example, the sample app will conditionally display a switch to enable geofencing for a favorite location in the ICFFavoritePlaceViewController.
