* 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.
