add a sketch of drone_logic and wiimote threads. NOTE: this commint does NOT compile
add variables and constants to make the project compile again. The functions added in the previous commit are just logic sketches, they don't do anything at all as of now
adjust formatting
add code to connect to the wiimote inside the wiimote thread. Include the bluetooth library and comment out the custom definition of bdaddr_t to avoid conflict with the cwiid library, at line 138 of ARDroneLib/VP_SDK/VP_Os/vp_os_types.h. Change Makefile at line 48 to include cwiid library.
prevent the video_recorder thread to start
add the retrieving and analysis  of inputs from wiimote (pression of button A or B, leds)
add part of the wiimote logic
add quitgui() to the gtk thread to try to land the drone when the gui close, but doesn't work... I need to work on this. Tested the wiimote logic to see if everything work as expected and obviously not. At the moment everything compile, but the score logic doesn't detect if the drone has been wounded...
add mutexes for drone_wounded and enemy_wounded variables. Use one of the mutex to share the drone_wounded between the wiimote thread and the score_logic thread. Now it seems to work, but it is really hard to hit the drone. Need further testing.
add some sleeping time inside the wiimote thread and the score_logic thread. Now works fairly well
remove every reference to gtk because it doesn't work. It makes the frame buffer freeze somehow if you add a custom thread. Use openCV instead. To intercept commands to the app use cvWaitKey(), to show point and information use cvPutText(). It isn't pretty, but it should work.
clean the code and move the openCV functions inside detection_functions.c
progress with the wiimote functions
add the complete score logic for subtracting point to the wiimote after being hit
add drone_logic thread and the logic behind the drone being hit
some minor change
add the score label over the openCV video stream
add function to detect hills and enemy and to calculate their distance from the drone
correct a spelling error in one variable and a slash where it wasn't suppose to be
add part of the drone logic to make the drone move autonomously. The code compile but it haven't been tested
