title: Why don't the marker titles show in my Google Maps API3 application?
body: <p>I added markers onto my map via this function.</p>
  
  <p><code>markers</code>: an array of Marker objects<br />
  <code>location</code>: a LatLng object<br />
  <code>myMarkerTitle</code>: the desired title for my marker<br /></p>
  
  <pre><code>// adds new markers to the map.
  function addAMarker(location, myMarkerTitle) {
      newMarker = new google.maps.Marker({
              position: location,
              map: map
      });
      newMarker.setTitle(myMarkerTitle);
      markers.push(newMarker);
  }
  </code></pre>
  
  <p>It adds markers on the map, but the titles I assigned to the markers do not show. Why?</p>
  
  <p>In the end, I want a map with markers scattered about with titles above them. When a client hovers over and clicks on a marker, more details also surface. Thank you.</p>
