KML support

Ok i succeed by editing the “function.js” file… But excuse my dust, i think it’s not the good way at all…

// Create the map
			try {
				$.bgmp.map = new google.maps.Map( $.bgmp.canvas, mapOptions );
				var ctaLayer = new google.maps.KmlLayer({
				    url: 'https://developers.google.com/maps/documentation/javascript/examples/kml/westcampus.kml',
				    map: $.bgmp.map
				  });
			} catch ( e ) {
				$( $.bgmp.canvas ).html( $.bgmp.name + " error: couln't build map." );

				if ( window.console ) {
					console.log( $.bgmp.prefix + 'buildMap: ' + e );
				}

				return;
			}

I’d like an advice on how to inject properly :

var ctaLayer = new google.maps.KmlLayer({
				    url: 'https://developers.google.com/maps/documentation/javascript/examples/kml/westcampus.kml',
				    map: $.bgmp.map
				  });

…Without breaking the updates..
