title: Creating Google Maps Marker including id attribute
body: <p>sorry for maybe a stupid question but I've read <a href="https://stackoverflow.com/questions/2564320/adding-ids-to-google-map-markers">Adding ID&#39;s to google map markers</a> before without success.</p>
  
  <p>I try to create a map with a number of markers. I would like to use jquery to work with this markers. Simple $('#marker1').doSomething(); 
  How is it possible to give this marker a valued id attribute? My really simple demo code will show you the way i tried to make it work.</p>
  
  <pre><code>function initialize() {
    var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
    var mapOptions = {
      zoom: 6,
      center: myLatlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    var map = new google.maps.Map(document.getElementById('map'), mapOptions);
    var marker = new google.maps.Marker({
        position: myLatlng,
        map: map,
        draggable: true,
        title: 'Hello World!',
    });
    marker.set("type", "point");
    marker.set("id", "ABC");
  }
  </code></pre>
  
  <p>Thanks a lot!</p>
