title: How can I set cluster marker function in Leaflet to display same coordinates markers when zoom is bigger than 13?
body: <p>I use <code>leafletJS</code> to <a href="https://jsfiddle.net/magi2109/91ugxw2r/" rel="nofollow noreferrer">show maps</a> with round about 100 markers. Some of these markers are located on exact the same position. MarkerB is above MarkerA so MarkerA isn't visible. when I use <code>markerClusterGroup</code> all markers display as shown as below.

  But I want when zoom is bigger 13 enable <code>ClusterMarker</code> and just perform on same coordinates marker(like markerA and MarkerB) and when zoom is smaller than 13 show noraml points.
  Is there a way?</p>
