title: Google MarkerClusterer: decluster markers below a certain zoom level?
body: <p>I'm using Google MarkerClusterer. I'd like to decluster all the markers whenever the map goes above zoom level 15. </p>
  
  <p>There is a <code>maxZoom</code> setting in the configuration options, but the <a href="http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerclusterer/1.0/docs/examples.html" rel="noreferrer">documentation does not make it clear what it is supposed to do</a>. </p>
  
  <p>I have tried setting it as follows, but the map remains clustered whatever zoom level I set the map to:</p>
  
  <pre><code>    new_mc = new MarkerClusterer(map, newco_markers, {
        maxZoom: 9
      });
  </code></pre>
  
  <p>Am I doing something wrong, have I misunderstood what the option is supposed to do, or is there another way to fix this?</p>
