/**
* Render class for rendering from XML. 
*
* This class should render documents from xml.
* The intended rendering modes will be HTML and
* the Adobe PDF format. Maybe at some point I 
* will make it possible to take a document from
* HTML to PDF, but this is unlikely. 
* 
* @author   Sean Grimes <metallic@noworlater.net>
* @version  $Id: Render.php,v 1.1.1.1 2001/07/19 00:20:52 zarzycki Exp $
* @todo     - Implement the HTML and PDF rendering modes
*           - Extend the parse() function to what is needed
*           - Implement filesystem commands
*           - Come up with the XML language syntax
*           - Provide a better class interface 
*          - Do some debugging
