Filter updater example.
Follow the URL's to find all the data you need, this is just the only thing you need to download, 
but make sure you DON'T put this filter in the stock-filters folder. 

Run the UpdaterTest filter once to find the first version, then click "Update Filters" below the filter panel. 
Once a message appears that filters have been updated, reload the filter tool and run the UpdaterText filter again to see the updated version.
