 * _wfsConnector - spiega bene
 *
 * To use wfsConnector:
 * 
 * 1) add a script tag to your page:
 * 
 * <script type="text/javascript" src="wfsConnector.js"></script>
 *
 * 2) create a new instance of _wfsConnector
 *
 * var l = new _wfsConnector( szName, bVisible, opacity, imageformat, bQueryable, 
 *                   server, version, layers, srs);
 *
 * 3) add it to the map
 *
 * ???? myKaMap.addMapLayer( l );
 *
 * For instance, assuming you have a form to input the parameters required:
 *
 * function addWFSData()
 * {
 *     var f = document.forms.wfs;
 *     var szName = f.wfsName.value;
 *     var server = f.wfsServer.value;
 *     var version = "1.0.0";
 *     var layers = f.wfsLayers.value;

 *     var wfsConn = new _wfsConnector( szName, server, version, layers);

 * }
 *
