	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 CCAtlasNode are valid in CCTileMapAtlas

	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: CCTMXTiledMap
