*/

//
// Google Maps loads many JS files asynchronously, so listening just to the first script load
// isn't enough to check if it is ready to be used, another problem is that the regular gmaps script 
// uses document.write, so we need to pass a `callback` parameter to make it not use `document.write` 
// and wait for the callback call.
// <http://code.google.com/apis/maps/documentation/javascript/basics.html#Async>
//
require(['async!http://maps.google.com/maps/api/js?sensor=false!callback'], function(){

	//Google maps is available and all components are ready to use.

	var mapDiv = document.getElementById('map-canvas');
	
	var map = new google.maps.Map(mapDiv, {
		center: new google.maps.LatLng(37.4419, -122.1419),
		zoom: 13,
		mapTypeId: google.maps.MapTypeId.ROADMAP,
		navigationControl: true,
		navigationControlOptions: {
			style: google.maps.NavigationControlStyle.SMALL
		}
	});
