*PARSES GROUP_DEFINE PARAMETERS FROM MADYMO AND REPLACES THE PARAMETERS WITH THE GIVEN VALUES*
==============================================================================================

Parses GROUP_DEFINE blocks in a Madymo input file (supplied as raw text) and replaces VAR_NAME/VALUE attribute pairs with user-supplied parameter values. Use this worker when you need to programmatically update Madymo model parameters without editing the deck file on disk.
