Add in a squareness test
This CL adds a "squareness" test to the firmware test suite.
Essentially, we've seen a few firmwares for touch devices come in
that don't have a squared resolution. eg: movement is compressed
in x or y. When this happens if you draw a 45 degree line on the
pad, the height and width will not be exactly the same, and it will
have a distorted angle..
This test has the robot/operator draw a 45 deg line on the pad,
then looks at the angle formed by these points. It should be right
about 45 if the resolution is correct.
BUG=none
TEST=manually tested.
