        Description
            For IxNetwork version >= 8.50.   
            Get stats by the statistic name or get stats by providing a view object handle.
            This method get stats using /api/v1/sessions/{id}/ixnetwork/statistics/view/{id}/data to get
            attributes columnCaptions, pageValues and totalPages. This method uses new API starting in 
            version 8.50.

        Parameters
            csvFile = None or <filename.csv>.
                      None will not create a CSV file.
                      Provide a <filename>.csv to record all stats to a CSV file.
                      Example: getStats(sessionUrl, csvFile='Flow_Statistics.csv')

            csvEnableFileTimestamp = True or False. If True, timestamp will be appended to the filename.
            displayStats: True or False. True=Display stats.
            ignoreError: True or False.  Returns None if viewName is not found.
            viewObject: The view object: http://{apiServerIp:port}/api/v1/sessions/2/ixnetwork/statistics/view/13
                        A view object handle could be obtained by calling getViewObject().

            viewName options (Not case sensitive):
               NOTE: Not all statistics are listed here.
                  You could get the statistic viewName directly from the IxNetwork GUI in the statistics.
