Read nodes as a tree.

Read nodes as a tree.

I encountered this too and made a fix in my fork. If it is ok, I can submit pull request.

I would imagine it breaks backwards compatibility, but it seems like a necessary change. I'll take a look if I get a chance and see what you did.

Oh, I see that you made it so that it doesn't return all that duplicate data in both the parents and the children. That's definitely an improvement. However, I was also hoping that the nodes would come back as a tree, and not flattened.

[lechat]

I think that since raw data nodes will still be wrapped in EtcdResult class, there is no point to return whole data, but just return immediate leaves. It is fairly trivial to traverse through leaves.

As for backwards compatibility, I thought about it and will try to make new method in EtcdResult for this feature once I get unit tests running on my machine and before I submit pull request.

@lechat thanks a bunch! I think backwards compatibility is a must, so you're on the right path :)
