 * Class TemplateAdaptor (XTemplate version)

 *
 * Description:
 * This class extends Barnabás Debreceni [cranx@scene.hu] XTemplate class
 * implementing methods and attributes needed for the CachedTemplate class.
 *
 * The adaptor class needs to implement the getTemplatesList() method that
 * returns an array with the names of the templates loaded, the init() 
 * method used to initialize the constructor of the parent template class,
 * and the getParsedDoc() method which returns the parsed document.
 *
 * Notes:
 * - This adaptor class overrides the original getfiles() method from
 *   XTemplate, in order to create the $TEMPLATES array which is returned
 *   by the getTemplatesList() method.
 *
 * Changes:
 * 2000/06/10 - Initial release.
 * 2000/07/17 - Documentation, new release.
