*COMPUTE ERROR BETWEEN TWO SETS OF CURVES BASED ON R2, MSD, NMAD, RE AND RETURN A DATASET*
==========================================================================================

Computes a scalar error metric between two sets of curves using one of eight supported measures (NMAD, MSD, RE, R², Fréchet, Euclidean, DTW, or Partial DTW) and returns the results as a tabular dataset. Use this worker to quantitatively compare simulation-vs-simulation or simulation-vs-test curve sets within a d3VIEW workflow.

     - Required
     - Description
   * - Reference Curves
     - ref_curves
     - vector
     - —
     - 
     - One or more reference (baseline) curves against which comparisons are made; accepts multiple vector curves — typically physical-test or trusted-simulation time-histories.
   * - Compare Curves
     - compare_curves
     - vector
     - —
     - 
     - One or more candidate curves to compare against the reference set; must be on a compatible x-axis domain for meaningful error computation.
   * - Error Type
     - type_of_error
     - scalar
     - nmad
     - 
     - Error metric to apply across each curve pair; choose from NMAD (default), MSD, RE, R², Fréchet Distance, Euclidean Distance, DTW, or Partial DTW — leave at default 'nmad' for a normalised, magnitude-independent comparison.
