Arm Subsystem and Operator Control

Software Requirements Arm:

Arm must keep its height(software must prevent the elevator from descending when raised) in up to 5 different positions:

- down for intake
- fully up to start/climb,
- slightly higher than ground for defense
- inside frame perimeter for more protection
- control panel (stretch goal))

Definition of Done:
Production software for the arm subsystem in the robot code, including:
- interface definitions, motors, sensors
- commands
- etc..
- tested independently
- merged and integrated with 2020 robot code in github
- ready for integration
