Detect button events

[Dylan-Powers]

As a robot driver, I want to be able to press a button for an unspecified amount of time and then release it, and for the robot to be able to detect a single button-down and/or button-up event so that actions do not happen more times than I want them too.

Definition of Done:
Can detect button pushed and button released events a single time per button press and run some code a single time when detected in a simple way to implement in multiple places.
