Returns:

DRL.

                      String worksheetName)

Looks for a named worksheet to find the decision tables on. Only works with XLS format spreadsheets (as they have multiple worksheets).

Parameters:

stream - The stream of the decision tables (spreadsheet) IN XLS format !!

worksheetName - The name of the worksheet that the decision tables live on.

Returns:
