*GET ENCLOSED AREA DIFFERENCE BETWEEN TWO CURVES*
=================================================

Computes the enclosed area difference between two XY curves by finding the region bounded between them. Use this worker when you need a scalar metric representing how much two curves diverge in area, e.g. for sim-vs-test correlation or hysteresis comparisons.

When to use

     - First XY curve (vector of coordinate pairs) forming one boundary of the enclosed region; accepts multiple curves in batch mode.

     - Second XY curve (vector of coordinate pairs) forming the other boundary of the enclosed region; must share the same axis domain as the first curve for a meaningful area difference.
