title: Google Maps API V3 - add event listener to all markers?
body: <p>There's got to be a way to add a listener to ALL MARKERS, currently I'm adding a listener to each one using a loop which feels really wrong...</p>
  
  <p>This feels wrong:</p>
  
  <pre><code>google.maps.event.addListener(unique_marker_id, 'click', function(){
      //do something with this marker...                   
  });   
  </code></pre>
