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

It can be as a replacement of CCLabel since it is MUCH faster.

CCLabelAtlas versus CCLabel:
- CCLabelAtlas is MUCH faster than CCLabel
- CCLabelAtlas "characters" have a fixed height and width
- CCLabelAtlas "characters" can be anything you want since they are taken from an image file

A more flexible class is CCLabelBMFont. It supports variable width characters and it also has a nice editor.
