/* BUGS: -->
Problem in betq():
if only two players remain in at start of final bets,
and if the first folds (an unnatural, but legal thing to do),
the second will bet before the program declares that only
one player remains in.
This does not materially affect the game.

The order of poker hands is as follows:\n\n\

Full house. (Three-of-a-kind plus a pair.)\n\
Flush. (Any 5 cards all of the same suit.)\n\

Pair.\n\n\
For tie breaking higher cards beat lower cards and the ace is high,\n\
