*COMPUTE THE SPRAGUE AND GEER ERRORS BETWEEN A REFERENCE CURVE AND A SET OF CURVES*
===================================================================================

Computes the Sprague and Geer error metrics between a single reference curve and a set of target curves, returning a matrix of error values. Use this worker to quantitatively assess how closely a batch of simulation or test curves match a reference signal.

     - 
     - The single reference (baseline) curve against which all target curves are compared; typically a physical test result or validated simulation curve supplied as an x/y vector.
   * - Target Curves
     - target_curves
     - vector
     - —
     - 
     - The set of target curves (e.g., multiple simulation runs) to be compared against the reference; supplied as a collection of x/y vectors, one Sprague-and-Geer error row is produced per curve.
