/** @brief CCTileMapAtlas is a subclass of CCAtlasNode.

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
