There are several errors related to beacon monitoring services.
I've taken some time to rewrite the entire class and align it with the Location services infrastructure.
This is a work in progress which will take some days (new version is currently on develop branch).

This post group the following errors:

• beaconManager stopMonitoring isn't really implemented. it doesn't stop the cllocationmanager for example #58 beaconManager stopMonitoring isn't really implemented. it doesn't stop the cllocationmanager for example
• beaconRequest state never set #57 beaconRequest state never set
• monitoring for ble beacons will never work as the callbacks filter based monitoredGeoRegions #56 monitoring for ble beacons will never work as the callbacks filter based monitoredGeoRegions
• monitorForBeaconFamily / monitorForBeacon -> Crashes with nil exception :: The initializers for the BeaconRequest object seem broken to me?! #52 monitorForBeaconFamily / monitorForBeacon -> Crashes with nil exception :: The initializers for the BeaconRequest object seem broken to me?!
