hs-pgms: Programmer's Mine Sweeper in Haskell

This is a Haskell implementation of Programmer's Minesweeper by
John D Ramsdell. See 
   http://www.ccs.neu.edu/home/ramsdell/pgms
for the original.

To add a new strategy, create a Haskell module that implements it, and
add it to the list in Strategies.hs. Then add the module itself it the
hs-pgms.cabal file and you're set. Two example strategies are provided,
SimpleStrat.hs and Strat1.hs (actually they're basically the same).

Note: The hs-pgms executable will launch a GUI by default. Run
hs-pgms --help to see its other capabilities.

Have fun!
