title: Open Leaflet Popup at bottom of marker
body: <p>I have placed several markers on my map and added popups to them. The following code is executed in a loop and works fine:</p>
  
  <pre><code>L.marker([
      item.Lat,
      item.Long
  ]).bindPopup(item.count + ' projects').addTo(map);
  </code></pre>
  
  <p>The markers are shown and popups open when you click them. However, the popup opens always on the top side of the marker. Is there a way to open in at the bottom (or on any side) of the marker? The <a href="http://leafletjs.com/reference.html#popup-options" rel="noreferrer">popup-options</a> in the Leaflet documentation do not seem to provide an option to do so.</p>
