The ArgParser control adds location bar querystring parsing functionality to an OpenLayers Map. When added to a Map control, on a page load/refresh, the Map will automatically take the href string and parse it for lon, lat, zoom, and layers information.

| OpenLayers. | |
| Functions | |
| setMap | Set the map property for the control. |
| setCenter | As soon as a baseLayer has been loaded, we center and zoom ...and remove the handler. |
| configureLayers | As soon as all the layers are loaded, cycle through them and hide or show them. |
{OpenLayers.Projection} Requires proj4js support. Projection used when reading the coordinates from the URL. This will
reproject the map coordinates from the URL into the map’s projection.
If you are using this functionality, be aware that any permalink which is added to the map will determine the coordinate type which is read from the URL, which means you should not add permalinks with different displayProjections to the same map.
Set the map property for the control.
setMap: function( map )
As soon as a baseLayer has been loaded, we center and zoom ...and remove the handler.

As soon as all the layers are loaded, cycle through them and hide or show them.
