	/** @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 CCBitmapFontAtlas. It supports variable width characters and it also has a nice editor.
