     The weakness should be obvious?  The file to be loaded and it's location
     I use a shared network drive to run this code from different machines, normally
     dev-ing from a PC.  When I ran the code on the laptop from a cafe it 
     immediately failed because the C: on the laptop was completely different
     to the PC, so the original file C:/tmp/KeyboardHandler.txt did not exist
    
     THIS IS A GREAT EXAMPLE OF WHY THE UNIT TEST AND CUT SHOULD NOT BE STRONGLY
     LINKED TO ANY IO - NETWORK, DB, AND FILE SYSTEM
