 * El módulo html pretende servir de herramienta para no tener que estar

 * mezclando la capa de código HTML con la capa de código en PHP en un

 * documento haciendo que así pueda utilizarse a modo de sistema de 

 * templates HTML.

 * ---------------------------------------------------------------------

 * Dependencias: Ninguna.

 * ---------------------------------------------------------------------

 * 09/12/11 - La clase html ( antes llamada parser ) ha sido reprogramada

 * 09/01/12 - Se ha separado el concepto de "página" del de parser por

 * módulo.

 * 09/01/12 - Se ha implementado la función "get" que devuelve un archivo

 * de template ( .tpl ) si no se le especifica una extensión ó un archivo

 * con extensión de la carpeta leaf/pages. Si es PHP se parsea.
