TileOverlay

###Add a TileOverlay A Tile Overlay is a set of images which are displayed on top of the base map tiles. These tiles are displayed like the base map tiles, but you can set the opacity of the tiles.

To add a tileOverlay, call addTileOverlay() method. The map.addTileOverlay() method takes a single overlay options object literal, specifying the initial properties of the tile overlay.

The following properties are available when constructing a TileOverlay:

Field Name	Type	Description
tileUrlFormat	String	The url of the tile images. You must include <x>,<y> and <zoom> strings into the URL format.
visible	Boolean	false if you want to hide the ground overlay.
zIndex	Number	Specify the zIndex. (Default: 0)
tileSize	Number	Specify the tile image size. (Default: 256)

map.addTileOverlay({
  // <x>,<y> and <zoom> are replaced with values
  tileUrlFormat: "http://tile.stamen.com/watercolor/<zoom>/<x>/<y>.jpg"
}, function(tileOverlay) {
  mTileOverlay = tileOverlay;
  map.showDialog();
});
