 * Revision 1.5  2006-06-21 12:35:45  jorpiell

 * Se ha a?adido la ventana de propiedades. Esto implica a?adir listeners por todos los paneles. Adem?s no se muestra la geomatr?a en la lista de atributos y se muestran ?nicamnete los que se van a descargar

 *

 * Revision 1.4  2006/06/14 07:57:19  jorpiell

 * Ya no se usa la estrategia ni se usa geotools para hacer el getFeature. Ahora se usa ?nicamente para el parseo de GML

 *

 * Revision 1.3  2006/05/25 15:32:01  jorpiell

 * Se ha a?adido la funcionalidad para eliminar el namespace de los tipos de atributos

 *

 * Revision 1.2  2006/05/25 10:32:21  jorpiell

 * Se ha renombrado la clase WFSFields por WFSAttributes porque era algo confusa

 *

 * Revision 1.1  2006/05/23 08:07:00  jorpiell

 * A?adido un m?todo para detectar el tipo de geometr?a
