PID: PID control template and GUI visualization

lib/pid.py from this repository is intended to be easily implemented into other projects.

GUI

gui.py is a visualization tool to see how pid gains affect the response characteristics.
To run the gui: python gui.py

• integral gain
• derivative gain
• derivative type (can differentiate either the error or the state)
