Internal Structure

• Each button spawns 2 threads, one for animation and one to watch the button
• main.py will eventually use the status reported back to it to drive system automation

A((main.py)) -- subprocess x4 --> B(main.py --button-to-run %button1-4% --animation %animationPattern% )
B -- STDOUT:Toggle Status --> A
B --> C[Big_Red_Button Class]
C -- thread --> F(Button Press)
C -- thread --> G(Light Animation)
