+/** 
+    A CCCamera is used in every CCNode.
+    Useful to look at the object from different views.
+    The OpenGL gluLookAt() function is used to locate the
+    camera.
+
+    If the object is transformed by any of the scale, rotation or
+    position attributes, then they will override the camera.
+ 
+	IMPORTANT: Either your use the camera or the rotation/scale/position properties. You can't use both.
+    World coordinates won't work if you use the camera.
+
+    Limitations:
+ 
+     - Some nodes, like CCParallaxNode, CCParticle uses world node coordinates, and they won't work properly if you move them (or any of their ancestors)
+       using the camera.
+     
+     - It doesn't work on batched nodes like CCSprite objects when they are parented to a CCSpriteBatchNode object.
+ 
+	 - It is recommended to use it ONLY if you are going to create 3D effects. For 2D effecs, use the action CCFollow or position/scale/rotate.
