Hi I tried to run the controller, but it's failed..not sure how to troubleshoot.

PS C:\Users\folder\grid-routing-battle> .\controller.py
Initializing bots.
Bots:
  Random Builder
  Checkpoint
  FaucetBot
  Connector
Running 100 rounds.
  Round 0

Do you have your Java executable in your PATH environment variable? That's all I can think of now. I know that the controller has trouble with Java submissions on Windows, and I haven't been able to fix it yet.

I issued a patch. I haven't tested it on Windows, but it should at least offer a more meaningful error message.
