 *  YMultiCellWeighScale Class: multi-cell weighing scale sensor control interface, available for

 *
 * The YMultiCellWeighScale class provides a weight measurement from a set of ratiometric
 * sensors. 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 cells themselves.
