//Returns an int indicating if the switch is on or not.
//If = 1, logical 1 is on the switch, else 0
//Parameters: switch_id -- one of the switch identifiers defined above

//Main program is a test function to display values of the switches
//on the LCD screen in real time.  Use this to calibrate switches so
//all are the same value when pressed / not pressed.
//Comment out main function to use with other modules.
