Arguments that brains' writers receive for their AI:
Session directory, symbol, timeLimit.
For example:
C:\Example\Game_5\O\ X 4,875

Before the contest you need to write this in Config.txt:
Player 1's folder, player 2's (absolute path to a player 2 folder) on a new line and so on.
Players' names are names of the .exe file.
On new lines timeLimits for all of the players.

If you want to add a random AI, write Random\some_random_name
as a new player.

For example:

C:\Example\Super_Hero
C:\Example\Potential_Winner
Random\Bot_David
TimeLimit = 4,875
TimeLimit = 5,0
TimeLimit = 1000
