com.google.gwt.maps.client.overlay.Marker
Marks a position on the map. It extends the ConcreteOverlay class and thus is added to the map using the MapWidget.addOverlay() method. A marker object has a point, which is the geographical position where the marker is anchored on the map, and an icon. If the icon is not set in the constructor, the default icon Icon.DEFAULT_ICON is used. After it is added to a map, the info window of that map can be opened through the marker. The marker object will fire mouse events and InfoWindow events.
