        public java.lang.String compile​(java.lang.String classPathResource,
                                InputType inputType)
        Convenience implementation, taking rules from the classpath. It is recommended to use the stream version, as you can then change rules dynamically. (that is a lot of the benefit of rule engines !).
        Parameters:
        classPathResource - full class path to the spreadsheet you wish to convert to DRL. Uses the first worksheet for the decision tables.
        Returns:
        DRL.

                                java.lang.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:
        DRL, ready to go.
