function setMarkers(map, locations) {
   Add markers to the map

   Marker sizes are expressed as a Size of X,Y
   where the origin of the image (0,0) is located
   in the top left of the image.

   Origins, anchor positions and coordinates of the marker
   increase in the X direction to the right and in
   the Y direction down.
  var image = {
    url: \'imagesbeachflag.png\',
     This marker is 20 pixels wide by 32 pixels tall.
    size: new google.maps.Size(20, 32),
     The origin for this image is 0,0.
    origin: new google.maps.Point(0,0),
     The anchor for this image is the base of the flagpole at 0,32.
    anchor: new google.maps.Point(0, 32)
  };
  var shadow = {
    url: \'imagesbeachflag_shadow.png\',
     The shadow image is larger in the horizontal dimension
     while the position and offset are the same as for the main image.
    size: new google.maps.Size(37, 32),
    origin: new google.maps.Point(0,0),
    anchor: new google.maps.Point(0, 32)
  };
   Shapes define the clickable region of the icon.
   The type defines an HTML <area> element \'poly\' which
   traces out a polygon as a series of X,Y points. The final
   coordinate closes the poly by connecting to the first
   coordinate.
  var shape = {
      coord: [1, 1, 1, 20, 18, 20, 18 , 1],
      type: \'poly\'
  };
  for (var i = 0; i < locations.length; i++) {
    var beach = locations[i];
    var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
    var marker = new google.maps.Marker({
        position: myLatLng,
        map: map,
        shadow: shadow,
        icon: image,
        shape: shape,
        title: beach[0],
        zIndex: beach[3]
