OpenLayers: Build a bounding box polygon and put it on an OpenLayers map

	function BuildBoundingBox(){
		var vectorLayer = new OpenLayers.Layer.Vector("Vector Layer");
		map.addLayer(vectorLayer);
		var proj = new OpenLayers.Projection("EPSG:4326");
		var style_green = {strokeColor: "#ff3300",strokeOpacity: 1,strokeWidth: 2,fillColor: "#FF9966",fillOpacity: 0.1};
