title: Leaflet adding an offset to marker
body: <p>I am getting the center of a leaflet feature to show its label. </p>
  
  <p>Then, I am specifying an offset when binding the label so it appears upper and righter. </p>
  
  <p>The thing is that i need to add the offset in the <code>entryJSON.getBounds().getCenter()</code> code. </p>
  
  <p>Is there a way of adding an offset in a leaflet latlong object? ( I can imagine something like entryJSON.getBounds().getCenter().offset([-10, -57]) but this is not working...)</p>
  
  <pre><code> var marker = new L.marker(entryJSON.getBounds().getCenter(), { opacity: 0.01 });
   marker.bindLabel('whatever here', {noHide: true, className: "info", offset: [-10, -57] });
  </code></pre>
