Working, but not perfect simulation code of the RC Pilot Controller. Code works for the square trajectory.

Merge branch 'anne_single_vehicle_sim' of https://gitlab.eecs.umich.edu/mmroma/coop_payload_sim into anne_single_vehicle_sim

Added method to change PID gains. Anne needs to finish connecting the params into the Simulink PID blocks.

This reverts commit 5e045d17.

Finished transferring all features to simulink. This branch is now ready to be merged back into master :)

Cleaning up folder structure and gitignoring extra simulink files and folders (still in progress through next commit or so).

Things are working for 5 quads, 1 payload! Still need to add back in wind, user forces, and disturbances, but things look good and it simulates very quickly for a 3 second hover trajectory

initial work on using simulink. things look promising for the single quad case, still need to plot everything but initial data looks good.
