Added a new script tracking for object tracking, it allows to learn object visually (associated with focus points) and send control commands to track the object on the horizontal axis (left/right)
Removed navigation .net
Added instead 2 new .net file for each different visual control, one for the optical flow (flot) and one for object tracking (tracking)

Update view_cell script to have faster processing, it does no longer recalculate values for difference of gaussians for each image but stock those values during initalization (the beginning takes ~1 min)
Update cam_usb.hwc to the right size of the image captured by the FOXEER camera
some small update on .gcd, .sh script ...

Updated drone script to send joystick inputs to the shared memory, and added a checkbox for visual control (on vmotors)
Added a new commands script to save experiments

Changed f_out "v_motors"'s channel name to "simulation" because it was confusing with (pixhawk.control)

+ small update on fly_monitor

Added a new script : object tracking. Part of it reuses view_cells, it allows learning of view cells and associates to an object.

Added a new script for view cell based on visual place cells script by Aminata Barry https://git.cyu.fr/promethe2/multimodal_pc

Added a new altitude measure in drone script but we can't use the new and the old one at the same time for now.
In order to revert back to the old altitude, just change to link between 'alt_2_offset' and 'throttle_err' to 'alt' and 'throttle_err' in the script drone.symb.
Note: since altitude_2 is relative to mean sea level and is from the barometer (drift and big variance), some tweaks are done to make it relative to our current starting point (checkbox start_alt) and filtered (mean value).

Add a new project that combine different promethe scripts (using themis): it reuses cam_f_out, drone_joyRemote and drone_flot (with some differences)

Little code correction (typo, print ...)

Changed fly_monitor indent from tab to space

Change droneRemote script name to drone_joyRemote (little bit more explicit), added global variable for more flexibility
Updated the readmes in consequence

Added possibility to study different altitude, yaw and motors curves for droneRemote by plotting them
Updated fly_monitor to limit high values (limited to 0.5 instead of 1) to send for drone control

Update Readme, update fly_monitor to include message frequency init for (distance sensor and compass heading)
