/**
 * Simple example intended to help users find the zero offset and natural direction of the sensor. 
 * 
 * These values can further be used to avoid motor and sensor alignment procedure. 
 * To use these values add them to the code:");
 *    motor.sensor_direction=Direction::CW; // or Direction::CCW
 *    motor.zero_electric_angle=1.2345;     // use the real value!
 * 
 * This will only work for abosolute value sensors - magnetic sensors. 
 * Bypassing the alignment procedure is not possible for the encoders and for the current implementation of the Hall sensors. 
 * library version 1.4.2.
