 =item * B<iterator>: A reference to a fresh ::iterator to use from the navmaps. The rendering will reflect the options passed to the iterator, so you can use that to just render a certain part of the course, if you like. If one is not passed, the renderer will attempt to construct one from ENV{'form.filter'} and ENV{'form.condition'} information.  =item * B<iterator>: A reference to a fresh ::iterator to use from the navmaps. The rendering will reflect the options passed to the iterator, so you can use that to just render a certain part of the course, if you like. If one is not passed, the renderer will attempt to construct one from ENV{'form.filter'} and ENV{'form.condition'} information, plus the 'iterator_map' parameter if any.
   
   =item * B<iterator_map>: If you are letting the renderer do the iterator handling, you can instruct the renderer to render only a particular map by passing it the source of the map you want to process, like '/res/103/jerf/navmap.course.sequence'.
   
 =item * B<navmap>: A reference to a navmap, used only if an iterator is not passed in. If this is necessary to make an iterator but it is not passed in, a new one will be constructed based on ENV info. This is useful to do basic error checking before passing it off to render.  =item * B<navmap>: A reference to a navmap, used only if an iterator is not passed in.

   =item * B<filterFunc>: A function that takes the resource object as its only parameter and returns a true or false value. If true, the resource is displayed. If false, it is simply skipped in the display. By default, all resources are showne.
