title: Link to marker in leaflet map from extern <a> tag
body: <p>I host a leaflet map and want to link to certain marker on that map from an a-element outside the map. I want the marker to behave like it was clicked, when the link is clicked.</p>
  
  <p>Clicking on </p>
  
  <pre><code>&lt;a href="#" onclick="WHATGOESHERE?"&gt;My Link&lt;/a&gt;
  </code></pre>
  
  <p>should activate my marker</p>
  
  <pre><code>L.marker([52.121935,11.627137], {icon: photomarker}).addTo(map)
  .bindPopup("&lt;b&gt;This is a marker&lt;/b&gt;")  ;
  </code></pre>
  
  <p>How can I achieve that? I got a hint, that it can be done with </p>
  
  <pre><code>marker.fire('click')
  </code></pre>
  
  <p>but I dont get it. Where should I put that? I am pretty new to javascript...</p>
