I'm going to work on this in my "spare" time.  ;-)  I recently noticed
that a couple of "cheap" tools were available that would measure a
cable.  Since the time to send a pulse and receive a response is very
short (nanoseconds), I had wondered how these tools could do it using an
inexpensive micro.
