/**
* Controls all the inner workings of the PID functionality
* Should be called by _timer
*
* Controls the heating element Relays manually, overriding the standard relay
* functionality
*
* The pid is designed to Output an analog value, but the relay can only be On/Off.
*
* "time proportioning control" it's essentially a really slow version of PWM.
* first we decide on a window size. Then set the pid to adjust its output between 0 and that window size.
* lastly, we add some logic that translates the PID output into "Relay On Time" with the remainder of the
* window being "Relay Off Time"
*
* PID Adaptive Tuning
* You can change the tuning parameters. this can be
* helpful if we want the controller to be agressive at some
* times, and conservative at others.
