 Changes:
 Turtles no longer monitor how many rows they've gone forward (no more rowsProgressed file)
 Master turtle simply waits for (numberSlaves) unique turtles to send messages saying
 they are ready and waiting. Slave turtles repeatedly send ready and waiting signals to prevent
 the sync problems we were having before.
