Added the cpp file to launch python script from ROS. Creating detector class in python to identify features of an ARDrone from an image. Created an empty file that will wrap the twist messages to be called with python (with ctypes). Also I am preparing for testing by creating a testing directory with plenty of (positive) images of the ARDrone and (negative) images of me! Skeletons have been made so that I can eventually test my detector in an automatic way.
