title: map.addOverlay in Google API v3
body: <p>is this the correcty way to change the add Overlay to v3? In V3 addOverlay is deprecated...and replaced with setMap?</p>
  
  <pre><code>    if (setContainerVisible == 1) {
          mapElements[lMapElementIndex]['visible'] = 1;
          //map.addOverlay(marker); v2
          marker.setMap(marker); // v3 ??
      }
  </code></pre>
