title: Prevent GMSMarker from repositioning camera view on tap
body: <p>I am creating a custom marker like below, </p>
  
  <pre><code>let am = GMSMarker(position: CLLocationCoordinate2DMake(22.213232, 144.332233))
  am.title = "some title"
  am.icon = UIImage(named: "marker_pointer")
  am.map = self.map
  </code></pre>
  
  <p>The above marker on tap, repositions the camera view and places itself in the centre of the map. </p>
  
  <p>Is there a way to prevent this behaviour? </p>
