title: jQuery maphilight change color on the fly
body: <p>I'm using this plugin <a href="http://davidlynch.org/js/maphilight/docs/" rel="nofollow noreferrer">http://davidlynch.org/js/maphilight/docs/</a></p>
  
  <p>But can't figure out, how to change color on the fly.
  It uses metadata plugin, and does it via class directive, but changes don't apply on fly.</p>
  
  <p>e.g.</p>
  
  <pre><code>class="{stroke:false,fillColor:'000000',fillOpacity:1,alwaysOn:true}"
  </code></pre>
  
  <p>and now I want to change color:</p>
  
  <pre><code>class="{stroke:false,fillColor:'00ffff',fillOpacity:1,alwaysOn:true}"
  </code></pre>
