title: Create a google maps link from API Map with multiple waypoint
body: <p>I have built a web app that uses the google maps v3 API to build a map with directions multiple waypoints. </p>
  
  <pre><code> jQuery.getJSON(driverURL, function(dData){
         var routeObject = {};
         var lat = dData.Location.lat;
         var lng = dData.Location.lng;
         routeObject.origin = new google.maps.LatLng(lat, lng);
         routeObject.destination = new google.maps.LatLng(endRoute.lat, endRoute.lng);
         routeObject.waypoints = waypoints;
         routeObject.travelMode = google.maps.TravelMode.DRIVING;
         routeObject.optimizeWaypoints = true;
         directionsService.route(routeObject, function(response, status) {
              if (status === google.maps.DirectionsStatus.OK) {
                   var directionsDisplay = new google.maps.DirectionsRenderer({
                         polylineOptions: {
                              strokeColor: colors[driverLines.length]
                         }
                   });
                   directionsDisplay.setMap(dMap);
                   directionsDisplay.setDirections(response);
              } else {
                   window.alert('Directions request failed due to ' + status);
              }
         });
    });
  </code></pre>
  
  <p>I have the Map, the waypoints, the start and the end all stored, but I'd like to be able to generate a google maps clickable link to the directions for this route that I can send to users. I can find how to send a link with a single marker, but not how to generate a map link with the full route direction. </p>
  
  <p>Any help appreciated.</p>
