        public void run()
        Sensor reader thread. Reads the current phase of the sensor and computes the new count. NOTE: There is a problem with this sensor when a read spans the point at which the sensor output changes from one value to another. The result of this can be a "ghost value". For instance if the read occurs when moving from state 2 to state 0 then a false reading of state 1 may be read. To reduce this problem a new state is not accepted until two consecutive reads return the same state.
