title: Is there a way to toggle MarkerClustererPlus
body: <p>I use MarkerClustererPlus for clustering markers on google map (v3)</p>
  
  <p>Is there a way to toggle clustering with a function.
  Namely I dont wont to effect markers, but only toggle visibility of cluster icons.</p>
  
  <p>For showing it we have property - repaint, but I couldnt find the property to hide clusters.</p>
