title: Getting lat/lng/zoom/yaw/pitch from Google Street View
body: <p>I have a Google map and street view based on provided lat/lng coordinates, zoom, yaw and pitch. I need to invoke a javascript to update a hidden field for each of these values whenever any of the details change from their default or when a button is clicked.</p>
  
  <p>So whenever the map/street view is zoomed in, panned, tilted etc it outputs the new details.</p>
  
  <p>How do I call the functions getPOV(), yawchanged(yaw:Number), pitchchanged(pitch:Number), and zoomchanged(zoom:Number) whenever the Street View is changed (similar to moveend for Maps)</p>
