Please add the ability to add a KML layer to a google map using the location type.

I manually added the following code to survey_runtime.js approx. line 195

var user_kmlLayer = new google.maps.KmlLayer('http://some_url/file.kml');
user_kmlLayer.setMap(map);

You would probably want to parameterize it to something like.

var user_kmlLayer = new google.maps.KmlLayer(url);
user_kmlLayer.setMap(map);

Thanks for consideration and keep up the good work.
