 As an option to MarkerClusterGroup you can provide your own function for creating the Icon for the clustered markers.
 The default implementation changes color at bounds of 10 and 100, but more advanced uses may require customising this.

+### Events
+
+If you register for click, mouseover, etc events on the MarkerClusterGroup you will get callbacks for both individual markers and clusters.
+Set your callback up as follows to handle both cases:
+
+```javascript
+markers.on('click', function (a) {
+	if (a.layer instanceof L.MarkerCluster) {
+		console.log('cluster ' + a.layer.getAllChildMarkers().length);
