 *  YWeighScale Class: weighing scale sensor control interface, available for instance in the

 * The YWeighScale class provides a weight measurement from a ratiometric sensor.
 * It can be used to control the bridge excitation parameters, in order to avoid
 * measure shifts caused by temperature variation in the electronics, and can also
 * automatically apply an additional correction factor based on temperature to
 * compensate for offsets in the load cell itself.
