Robots Exercise #2

Examine the Robot class API documentation.
What method will give you the current direction the 
robot is facing?

Add another static method to oopintro.BeckersRobots.java:
Method name: faceDirection()
Arguments: a Robot object, a Direction to face
Return value: none
This method should make the Robot parameter turn left 
until it's facing the desired Direction (the one stored in
the Direction parameter).
