[CRUSH-build] driver feedback - another thing to consider

[Bill Bennett]

Parking in front of the corner goal to dump will be a challenge for the 
driver. He's 60' away and has to part the robot as well as possible with its 
side parallel to the wall and 25 inches from the wall, in order for most of 
the balls to roll through the goal hole when we dump. If we could have some 
kind of driver feedback that indicated these two metrics (angle to the wall 
and distance from the wall) this would help.
