Hi Jianwu,
Thanks, I merged in your changes to DirectoryListing.  One thing I changed
was the name of the parameter from allowEmptyDir to allowEmptyDirectory
as we don't use appreviations in Ptolemy parameter names.

I also created a couple of tests and added you as a contributor to
that file.

Note that to get the change you will need to update
kepler/ptolemy/module-info/revision.txt to 58597.
This should happen automatically, but there is a bug that is not
updating the ptolemy revision number.
