+* Manager class that manage all operation related to Bluetooth connection. This
+* class provide interface for other object to connect and disconnect to bluetooth
+* device. It also provide observer interface to other object to get device
+* connection status change. This class also provides observer interface for other
+* object get messages from connected BT device.
+* The class defines connection process that defines how
+* to connect to bluetooth device. Each process contains handlers that handle
+* BT connection activities.
