title: Google Maps and Markermanager throws error
body: <p>I'm using google map API along with the <a href="http://code.google.com/apis/maps/documentation/overlays.html#Marker_Manager" rel="nofollow noreferrer">MarkerManager</a>. I load the 2 javascript libraries by JQuery.</p>
  <p>Here is my Javascript:</p>
  <pre><code>function initialize() {
      $.getScript('http://gmaps-utility-library.googlecode.com/svn/trunk/markermanager/release/src/markermanager.js');
      $.getScript('http://maps.google.com/maps?file=api&amp;amp;v=2&amp;async=2&amp;callback=mapLoaded&amp;amp;sensor=true_or_false&amp;amp;key=ABC');
      
  }
  function mapLoaded() {
      if (GBrowserIsCompatible()) {
          map = new GMap2(document.getElementById(&quot;map_canvas&quot;));
          map.setCenter(new GLatLng(18, -77.4), 13);
          map.setUIToDefault();
  
          var mgr = new MarkerManager(map);
          mgr.addMarkers(getWeatherMarkers(), 5); //gets some marker from another function
          mgr.refresh();
  
      }
  }
  </code></pre>
  <p>The error I get in firebug javascript debugger is:</p>
  <p>GBounds is not defined
  [Break on this error] GBounds.prototype.containsPoint = function(point) {\nmarkerma...109501758 (line 377)</p>
  <p>me.getMapGridBounds_ is not a function
  [Break on this error] me.shownBounds_ = me.getMapGridBounds_();\n
  markerma...109501758 (line 106)</p>
  <p>This error also occurs if I load the javascript library statically.</p>
  <p>Thanks,</p>
