title: Styling MarkerClusterer Icons?
body: <p>I am using the MarkerCluster.js to create clustering in my google maps api. The clusters work how I want them however I want to style differently than yellow, blue and red circles. I was trying to use the MarkerStyleOptions and it says you have an array of styles with the smallest cluster icon first and the biggest last. I tried to create this below but I am getting really confused about what syntax to use and can't find any good examples.</p>
  
  <pre><code>var clusterStyles = [
      [opt_textColor: 'white'],
      [opt_textColor: 'white'],
      [opt_textColor: 'white']
  ];
  
  var mcOptions = {
      gridSize: 50,
      styles: clusterStyles,
      maxZoom: 15
  };
  var markerclusterer = new MarkerClusterer(map, cluster, mcOptions);
  </code></pre>
