In this Challenge, you will program your VEX IQ robot to navigate through 3 different intersections,
each of which has a traffic signal which will start as red, then switch to green.
The robot must stop at each red signal, and wait until it switches to green before moving forward again.
The robot does not need to stop on its own after passing through all three intersections
(it can be stopped by hand).
