* COMPUTE THE AREA WEIGHTED DIFFERENCE USING MAX-MIN NORMALIZE*
===============================================================

Computes the area-weighted difference between two curves using max-min normalization, returning a single scalar metric. Use this worker to quantify the normalized area gap between a baseline and a comparison curve (e.g., sim vs. test).

     - 
     - Base (reference) curve supplied as an X-Y vector; typically the simulation or physical-test baseline against which Curve 2 is compared. Accepts multiple curves when batch comparison is required.
   * - Curve 2
     - curve2
     - vector
     - —
     - 
     - Second X-Y vector curve to compare against Curve 1; represents the candidate or alternative curve (e.g., a different simulation run or a physical channel).
   * - Number Of Points
     - num_dig
     - scalar
     - 0
     - 
     - Number of interpolation/resampling points used when synchronising the two curves prior to area integration; defaults to 0, which preserves the original curve resolution.

     - scalar
     - Scalar area-weighted difference (dimensionless, max-min normalised) between Curve 1 and Curve 2; a value of 0 indicates perfect agreement and larger values indicate greater divergence.
