                          10/15/2020 Damn pandemic still going on.
                                    
This is a really simple test/demo program for the Left Coast lilParser.
In the serial monitor..
      
      Type : on    to turn on the LED.
      Type : off   to turn it off again.
      
In order to run this you will need, along with this library : LC_baseTools
LC_baseTools can be found in in the Arduino library manager.

Or here : https://github.com/leftCoast/LC_baseTools

                  LEDOff,     // What the other commands are, how they work and what they do.

         case LEDOff    : digitalWrite(LED_PIN, LOW);  break;  // Turn the LED off by making the voltage LOW
