This command is useful when you don't already know what direction a motor is
going.
Consider the following contrived example: A Robot w/a single light sensor is
supposed to drive back and forth between two black lines. Additionally, this
robot is supposed to start in a random direction. Coding this using flip is
substantially tighter than using "Motor A forward".
This topic actually brings up problem I keep running into. Is there any way to
programatically detect which direction a motor is set to turn?
Thanks,
Tom
