BLE framework meets swift

[FernandoReynoso]

BLE framework migrated to swift.
Including the following:

Public methods
func startScanning(timeout: Double) -> Bool
func connectToPeripheral(peripheral: CBPeripheral) -> Bool
func disconnectFromPeripheral(peripheral: CBPeripheral) -> Bool
func read()
func write(#data: NSData)
func enableNotifications(enable: Bool)
func readRSSI(completion: (RSSI: NSNumber?, error: NSError?) -> ())

Delegate methods
func bleDidUpdateState()
func bleDidConnectToPeripheral()
func bleDidDisconenctFromPeripheral()
func bleDidReceiveData(data: NSData?)
