Matthew White / Robocup PCB - History

preliminary version of revC

may not be necessary if the revB can be used with the current mechanical
design

Breakbeam revB update

added planes on top layer to maximize adhesion
added anchored support pads for diode tensioner (only use if necessary)
added offset plane near the mounting holes to make the bottom side level
(the bottom plane for the anchor will have a non-zero height)
