It knows how to render a map based of tiles.
The tiles must be in a .PNG format while the map must be a .TGA file.

For more information regarding the format, please see this post:
http://www.cocos2d-iphone.org/archives/27

All features from AtlasNode are valid in TileMapAtlas

IMPORTANT:
This class is deprecated. It is maintained for compatibility reasons only.
You SHOULD not use this class.
Instead, use the newer TMX file format: TMXTiledMap
