-     * (code)
-     * map.events.register(type, obj, listener);
-     * (end)
-     *
-     * Listeners will be called with a reference to an event object.  The
-     *     properties of this event depends on exactly what happened.
-     *
-     * All event objects have at least the following properties:
-     * object - {Object} A reference to map.events.object.
-     * element - {DOMElement} A reference to map.events.element.
-     *
-     * Browser events have the following additional properties:
-     * xy - {<OpenLayers.Pixel>} The pixel location of the event (relative
-     *     to the the map viewport).
-     *
-     * Supported map event types:
-     * preaddlayer - triggered before a layer has been added.  The event
-     *     object will include a *layer* property that references the layer  
-     *     to be added. When a listener returns "false" the adding will be 
-     *     aborted.
-     * addlayer - triggered after a layer has been added.  The event object
-     *     will include a *layer* property that references the added layer.
-     * preremovelayer - triggered before a layer has been removed. The event
-     *     object will include a *layer* property that references the layer  
-     *     to be removed. When a listener returns "false" the removal will be 
-     *     aborted.
-     * removelayer - triggered after a layer has been removed.  The event
-     *     object will include a *layer* property that references the removed
-     *     layer.
-     * changelayer - triggered after a layer name change, order change,
-     *     opacity change, params change, visibility change (actual visibility,
-     *     not the layer's visibility property) or attribution change (due to
-     *     extent change). Listeners will receive an event object with *layer*
-     *     and *property* properties. The *layer* property will be a reference
-     *     to the changed layer. The *property* property will be a key to the
-     *     changed property (name, order, opacity, params, visibility or
-     *     attribution).
-     * movestart - triggered after the start of a drag, pan, or zoom. The event
-     *     object may include a *zoomChanged* property that tells whether the
-     *     zoom has changed.
-     * move - triggered after each drag, pan, or zoom
-     * moveend - triggered after a drag, pan, or zoom completes
-     * zoomend - triggered after a zoom completes
-     * mouseover - triggered after mouseover the map
-     * mouseout - triggered after mouseout the map
-     * mousemove - triggered after mousemove the map
-     * changebaselayer - triggered after the base layer changes
-     * updatesize - triggered after the <updateSize> method was executed

-     *   very worthy of mention is that simply removing a layer from a map

-     *    
-     *     A simple solution to this is simply to call destroy() on the layer.
-     *     the default OpenLayers.Layer class's destroy() function
-     *     automatically takes care to remove itself from whatever map it has
-     *     been attached to.
