Well, I have code for both methods.  One for polling and another for
checking the interrupt flag.  It would require massive restructuring to use
an ISR routine.  I don't want to do that, so I was just testing to see if
enabling the interrupt and then polling the ADIF flag (which should work)
*would* work.  It doesn't.  I couldn't get the Go\Not Done bit flip to work,
so I threw in some code to see if it would complete with the ADIF flag.

Neither seem to allow the conversion to complete.  It just goes in to the
loop and hangs.
