TileLayer Class
The TileLayer allows you work with a cached map service exposed by the ArcGIS Server REST API and add it to a Map
as a tile layer. A cached service accesses tiles from a cache instead of dynamically rendering images. Because they
are cached, tiled layers render faster than MapImageLayers. To create an instance of TileLayer, you must reference
the URL of the cached map service.
