*GET THE CELL VALUE FROM GIVEN DATASET*
=======================================

Extracts a single cell value from a dataset given a row and column index. The column may be referenced by zero-based integer position or by column name. Use this worker when you need to pull one scalar value out of a tabular dataset for downstream logic.

When to use

     - The input tabular dataset from which a cell value will be extracted; must be a structured dataset with at least one row and one column.
   * - Row Index
     - row_index
     - scalar
     - 0
     - 
     - Zero-based integer index of the target row (e.g. 0 = first row); defaults to 0.
   * - Col Index
     - col_index
     - scalar
     - 0
     - 
     - Zero-based integer index or string column name of the target column (e.g. 0 = first column, or 'stress' to reference by header); defaults to 0.
