// Implements the Bluetooth 4.0 LE Peripheral (Server) interface
//
// This service works by using CoreBluetooth CBPeripheralManager to expose
// a Bluetooth Peripheral (Server) that contains one primary |service|.
//
// The service has one subscribable/notifable |characteristic| that is
// referenced by UUID "c0de".
//
// Any Bluetooth 4.0 LE Central (aka. Client) that subscribes to this peripheral
// will cause a delegate message to be sent. This in turn will allow the
// peripheral to respond with data by calling the |sendToSubscribers| method.
