Calibrate Steering Column

This test calibrates the steering column. When the calibration is run, the steering column will first move all the way in, then move out to the endpoint. Next, the up/down axis will be calibrated in the same manner. The calibration routine is used to set the zero position of both axes and to determine the number of motor encoder counts it takes to reach the other end point of the column's travel.
