 - cam_f_out: sends camera input (or any capture device opened in /dev/video*) to f_out (shared memory)
 - drone_joyRemote: reads and updates the shared memory according to joystick inputs and checkboxes (added plot for altitude and compass heading control)
 - drone_test: using checkboxes, updates the shared memory for several drone actions
 - drone_flot: reads input image in f_in, adds a visual control of the drone using optical flow, through shared memory
