title: Clustering markers from csv with leaflet and omnivore
body: <p>I'm trying to cluster data from csv parsed with omnivore and with the markercluster plugin but nothing happens. When i'm not using the plugin, I can see all my markers so...</p>
  
  <p>I saw many examples <a href="http://bl.ocks.org/wboykinm/9374994" rel="nofollow noreferrer">like this</a> but they all use mapbox and I build a pure leaflet map. I've also <a href="https://stackoverflow.com/questions/17005784/clustering-markers-on-mapbox-leaflet?rq=1">tried this</a> but my problem is still here.</p>
  
  <p>All I have in my console is a "syntax error" for my csv but it's not the core problem. </p>
  
  <p>My csv looks like this : </p>
  
  <pre><code>date,dcomiris,latitude,longitude,infra,iris,com,name
  2014-01-01,600570101,49.4295880722704,2.08997269112341,7871F,Cathedrale-Universite,60057,Beauvais
  </code></pre>
  
  <p>My code looks like this for now :</p>
  
  <pre><code>var map = L.map('map').fitBounds([[49.072667, 1.653442],[49.737499, 3.158569]]);
  
  L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
      attribution: '&amp;copy; &lt;a href="http://www.openstreetmap.org/copyright"&gt;OpenStreetMap&lt;/a&gt;'
  }).addTo(map);
  
  var points = omnivore.csv('my.csv');
  // points.addTo(map);
  
  var markers = new L.markerClusterGroup({showCoverageOnHover:false});
  markers.addLayer(points);
  map.addLayer(markers); 
  </code></pre>
  
  <p>What did I miss?</p>
