+/**
+ * Class: OpenLayers.Marker
+ * Instances of OpenLayers.Marker are a combination of a 
+ * <OpenLayers.LonLat> and an <OpenLayers.Icon>.  
+ *
+ * Markers are generally added to a special layer called
+ * <OpenLayers.Layer.Markers>.
+ *
+ * Example:
+ * (code)
+ * var markers = new OpenLayers.Layer.Markers( "Markers" );
+ * map.addLayer(markers);
+ *
+ * var size = new OpenLayers.Size(21,25);
+ * var offset = new OpenLayers.Pixel(-(size.w/2), -size.h);
+ * var icon = new OpenLayers.Icon('http://www.openlayers.org/dev/img/marker.png', size, offset);
+ * markers.addMarker(new OpenLayers.Marker(new OpenLayers.LonLat(0,0),icon));
+ * markers.addMarker(new OpenLayers.Marker(new OpenLayers.LonLat(0,0),icon.clone()));
+ *
+ * (end)
+ *
+ * Note that if you pass an icon into the Marker constructor, it will take
+ * that icon and use it. This means that you should not share icons between
+ * markers -- you use them once, but you should clone() for any additional
+ * markers using that same icon.
