Do any clean up necessary to allow this instance to be used again.
<p/>
<p>When we get here, the Zip file has been closed and all we
need to do is to reset some globals.</p>
<p/>
<p>This method will only reset globals that have been changed
during execute(), it will not alter the attributes or nested
child elements.  If you want to reset the instance so that you
can later zip a completely different set of files, you must use
the reset method.</p>
