Alexander Holgate MonahanThat's a very good answer! That's the
   answer I had too. I have an unfortunate suspicion that no matter
   WHO I ask, up to the greatest workers in mathematics, quantum
   mechanics, atom smashers, that will be their answer too. I'm
   *hoping* for something different but I have a suspicion that
   "That's a very good question" may be the ultimate, final answer.
