Offers a node design for interacting with the Java Zookeeper client.

                 Key: ZOOKEEPER-679
             Project: Zookeeper
          Issue Type: New Feature
          Components: java client, tests
            Reporter: Aaron Crow
            Priority: Minor

Following up on my conversations with Patrick and Mahadev 

This patch includes the implementation as well as unit tests. The first unit 
test gives a simple high level demo of using the node API.

The current implementation is simple and is only what I need withe current 
project I am working on. However, I am very open to any and all suggestions for 

This is a proposal to support a simplified node (or File) like API into a 
Zookeeper tree, by wrapping the Zookeeper Java client. It is similar to Java's 
File API design.

Although, I'm trying to make it easier in a few spots. For example, deleting a 
Node recursively is done by default. I also lean toward resolving Exceptions 
"under the hood" when it seems appropriate. For example, if you ask a Node if 
it exists, and its parent doesn't even exist, you just get a false back (rather 
than a nasty Exception).

As for watches and ephemeral nodes, my current work does not need these things 
so I currently have no handling of them. But if potential users of  the "Node 
a.k.a. File" design want these things, I'd be open to supporting them as
