   4  simulate.py - simulation script for the 2012 UCC Programming Competition
   5         NOTE: This is not the manager program for a stratego game
   6         It merely calls the manager program as appropriate, and records results
   7         Plays exactly ONE round, but does not overwrite previously played rounds
   8         eg: run once to generate round1.results, twice to generate round2.results etc
   9         Also generates total.scores based on results from every round.
