2012-12-23 Created a better class for handling 1D motion
2012-12-23 Moved code to use the LinearMotionController instead of redundant code.
2013-12-23 Revolution test revolve now turns 1/16th of a revolution.
Swapped out mass of Cartesian Controller loop code, since those loops are handled by the individual 1D controllers.
Suport for 2 exturders, and reorganized code.
Motor Z primary direction was incorrect.
2013-12-23 Motor on Z axis was strting off in the wrong direction.
2013-12-23 Change api from testMotorX -> testMotors which tests X,Y,Z by turning 1/16th of a revolution, back and forth, and then calibrates the plane.
2013-12-23 Version bump with changed serial api.
