Description: Runs main functions in interface between instrument signal and app message.
             If lab instrument fails, it sends a signal which is then translated into some
             input by the Raspberry pi which then throws that input at the program. This 
             input is picked up by detect_signal(), which then returns True (False if
             nothing is picked up). This then calls send_message(signal), which depending
             on boolean signal, lets the user know if the lab intrument ran into a problem
             or ran succesfully (no signal sent).
