Initial rewrite of the base duo ros driver class
Fixed error with DUOCallback function. Need to figure out how to put that function outside the node.cpp file, in the driverDUOstereo.cpp class
Initialize DUO works now. Now i will work on rewriting the image publisher function.. this will be interesting.
Implemented Singleton instance to be able to access DUOStereoDriver private members inside the DUOCallback function.
Finished rewriting the duo driver. The 'set_camera_info' service is now being advertised by the duo_node for both the left and right cameras.
