This can be helpful in determining whether a given node is in the place in the hierarchy
that you expect it to be. If it isn't, this tells you where it is or whether it's not there at all.
In this case, the CCScene has a single CCNode child node, which in turn has a child
CCNode whose name is background .
Tip The formatting and logged properties may not suit all purposes. You may
want to make a copy of the walkSceneGraph method found in the
CCNode+Debug.m file and modify it to generate the output you find more
helpful.
