     * range [x-1, x).
     * 
     * - Setting this to 1 makes the absolute position unsigned [0, 1)
     * - Setting this to 0.5 makes the absolute position signed [-0.5,
     * 0.5)
     * - Setting this to 0 makes the absolute position always negative

     * 
     * Many rotational mechanisms such as arms have a region of motion
     * that is unreachable. This should be set to the center of that
     * region of motion, in non-negative rotations. This affects the
     * position of the device at bootup.
     * 
     * \details For example, consider an arm which can travel from -0.2 to
     * 0.6 rotations with a little leeway, where 0 is horizontally
     * forward. Since -0.2 rotations has the same absolute position as 0.8
     * rotations, we can say that the arm typically does not travel in the
     * range (0.6, 0.8) rotations. As a result, the discontinuity point
     * would be the center of that range, which is 0.7 rotations. This
     * results in an absolute sensor range of [-0.3, 0.7) rotations.
     * 
     * Given a total range of motion less than 1 rotation, users can
     * calculate the discontinuity point using mean(lowerLimit,
     * upperLimit) + 0.5. If that results in a value outside the range [0,
     * 1], either cap the value to [0, 1], or add/subtract 1.0 rotation
     * from your lower and upper limits of motion.
     * 
     * On a Talon motor controller, this is only supported when using the
     * PulseWidth sensor source.
