def url_to_local(urlpath):

"""Given a URL path (part of a URL query string, see below), returns a

tuple of

* the username of the student whose directory is being browsed

* the absolute path in the file system where that file will be

found within the student directories.

urlpath: Part of the URL, but only the part *after* the application. For

instance, given the URL "/ivle/browse/joe/home/mydir/myfile", urlpath will

be just "joe/home/mydir/myfile". The expected result is something like

("joe", "/home/informatics/jails/joe/home/svn/mydir/myfile").

Note that the actual location is not guaranteed by this interface (this

function serves as a single point of control as to how URLs map onto

student directories).

Returns (None, None) if the path is empty.
