title: How to use containsLocation in Google maps geometry library.
body: <p>I am trying to use the <code>containsLocation</code> from the Google geometry library, but can't get it to work...</p>
  
  <pre><code>var point = new google.maps.LatLng(51.331, 3.538);
  var poly = [
   new google.maps.LatLng(51.401818509550615, 3.547626782103622),
   new google.maps.LatLng(51.397574277049365, 3.563607598960424),
   new google.maps.LatLng(51.398540111384975, 3.567880788749134),
   ... // it is a lot bigger
  ];
  
  if(google.maps.geometry.poly.containsLocation(point, poly) == true) {
   alert("yes");
  }
  </code></pre>
  
  <p>The Javascript console gives an error, but that points to a function in Google's lib. So I assume the problem should lie somewhere in this function.</p>
