Added:
mainLoop()
eventLoop()
Pseudo code main thread.

Changed:
writeMessage(): Added time to printed/broadcasted message.
turtleMove()
turtleTurn()
Probably a lot more that I can't remember.

Removed:
turtleFace(): Commented out. Not quite sure how to use it in the current implementation.
fuel value: No point in having a value when turtle.getFuelLevel() does the same.0
