*SCALE THE X-VALUES AND Y-VALUES BY THE BY A CURVE*
===================================================

Scales a collection of curves element-wise by a reference scaling curve, multiplying both x- and y-values of each input curve by the corresponding values of the scaling curve. Use this worker when you need to apply a curve-shaped gain or weighting function across a set of curves rather than a single scalar factor.

     - 
     - One or more input curves (x/y vector pairs) whose x- and y-values will be scaled; accepts multiple curves simultaneously.

     - A single reference curve whose x- and y-values are used as the point-wise scaling factors applied to each curve in `curvestobescaled`.
