title: Leaflet markercluster- change color of coverage on hover
body: <p>I'm trying to change the color of the coverage on hover (showCoverageOnHover) in the Leaflet markercluster plugin. I can't find this in the <a href="https://www.npmjs.com/package/leaflet.markercluster" rel="nofollow">documentation</a>. </p>
  
  <p>What I want to achieve is to change the color of the coverage on hover from blue to something else. For example, when you hover with the mouse over a cluster icon in <a href="http://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-realworld.10000.html" rel="nofollow">this example</a>.</p>
