 * The Gyro class tracks the robots heading based on the starting position. As the robot
 * rotates the new heading is computed by integrating the rate of rotation returned
 * by the sensor. When the class is instantiated, it does a short calibration routine
 * where it samples the gyro while at rest to determine the default offset. This is
 * subtracted from each sample to determine the heading.
