Wrote python script to simulate a round

simulate.py identifies agents, pits them against each other, and keeps track of scores using files.

Needs the "info" files in AI directories to determine what file to execute.

Spent a lot of time learning/failing at setting up vm on clownfish, called mufasa.
Will finish setting up vm later.

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