+/**
+ * Use a rate gyro to return the robots heading relative to a starting position.
+ * 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. This gyro class must be used with a channel that is
+ * assigned one of the Analog accumulators from the FPGA. See AnalogInput for
+ * the current accumulator assignments.
+ *
+ * This class is for gyro sensors that connect to an analog input.
