023     *  This is a simple interface which is implemented by a number of JSPWiki
024     *  components to signal that they should not be included in things like
025     *  module listings and so on.  Because JSPWiki reuses its internal module
026     *  mechanisms for its own use as well (e.g. RenderingManager uses a PageFilter
027     *  to catch page saves), it's sort of dumb to have these all appear in the
028     *  "installed filters" list.
029     *  <p>
030     *  A plugin developer should never implement this interface.
