*GET CURVES BY INDEXES. USEFUL FOR EXTRACTING A CURVE FOR A COLLECTION OF CURVES USING THE ORDER.*
==================================================================================================

Extracts one or more curves from a collection by their zero-based positional indexes. Provide a comma-separated list of indexes to retrieve the corresponding curves in order. Use this worker when you need to select specific curves from a larger group by position rather than by name or attribute.

     - 
     - Input collection of curves (CurveGroup / vector) from which individual curves will be selected; accepts multiple curves.
   * - Indexes Separated By Commas
     - indexesseparatedby_commas
     - string
     - 0
     - 
     - Zero-based positional indexes of the curves to extract, supplied as a comma-separated string (e.g. "0,2,4"); defaults to "0" (first curve).
