*INTERPOLATE THE CURVE TO GET Y-VALUES FOR NEW X-POINTS*
========================================================

Interpolates a source curve onto a new set of x-points by pairing it with a reference old-y curve and a new-x curve, returning the interpolated y-values at the new x-positions. Use this worker when you need to resample or remap a curve onto a different x-axis grid provided by another curve object.

     - The source curve supplying the original x-axis points (dimensionless index or physical units matching the old-y curve); passed as a vector or CurveGroup (first curve is used).

     - The curve supplying the original y-values that correspond to the old x-points; passed as a vector or CurveGroup (first curve is used).

     - curvewithnew_x-points
     - vector
     - —

     - The curve whose x-values define the new grid onto which the y-values will be interpolated; passed as a vector or CurveGroup (first curve is used).
