Code used to handle the multi-camera system used to deal with the Spectrographic Analysis task of the NASA HERC.
camera.py: Base code that takes one picture from each camera on execution. Runs once.
camera-button-only.py: Code that waits for button input before taking the four pictures. Runs indefinitely.
camera-heartbeat.py: Code that, in addition to the above, will occasionally print to the shell to let the user know that the script is still running.
