title: Howto getCenter in gmap from list of markers?
body: <p>How do I use the getCenter() function with a list of picked markers from my gmap(3.0)?</p>
  
  <p>Right now im trying this approach</p>
  
  <pre><code>Ext.each(myRecords, function (r) {
  if (...) {
  myArray.push(new google.maps.LatLng(r.get('Latitude'), r.get('Longitude')));
  }
  });
  </code></pre>
  
  <p>Is there a easy way to get the furthest markers from that array? If i can get that i might be able to do:</p>
  
  <pre><code>var myLatLng = ...   
  var bounds = new google.maps.LatLngBounds();
  bounds.extend(myLatLng);
  bounds.getCenter(); 
  </code></pre>
