title: How to change the cursor on hover in openlayers 3?
body: <p>I managed to add interactivity to a feature layer added from a remote GeoJSON resource. When I click on a feature I get its ID, fire an AJAX request and display some relevant info about the feature, on the page outside of the map area.</p>
  
  <p>I used a <code>Select</code> interaction.</p>
  
  <p>I would like to make it even clearer to the user that he can click on the features on the map. Is there any way I can change the mouse cursor to "cursor" of "hand" when the mouse hovers a feature contained in a <code>ol.layer.Vector</code> ?</p>
  
  <p>I couldn't find anything in the doc, on this site or by googling.</p>
