*COMPUTE THE DIFFERENCE DIFF NORMALIZED TO THE FIRST CURVE AND RETURN IN PERCENTAGE*
====================================================================================

Computes the normalized difference between two curves, subtracting the second curve's values from the first and normalizing the result to the first curve, returning the output as a percentage. Use this worker when you need a relative (percentage) deviation between two curves rather than an absolute difference.

     - The reference (base) curve from which values are subtracted and against which the normalization is applied; supply as a vector/curve object — this acts as the denominator in the normalization.
   * - Curve Whose Values Will Be Used To Subrtract
     - curvewhosevalueswillbeusedtosubrtract
     - vector
     - —
     - 
     - The curve whose y-values are subtracted from the reference curve (Curve 1); supply as a vector/curve object of matching length or x-domain.
