Develop higher order patterns library

[davidledwards]

The idea is to develop a functional library layered over zookeeper-client that implements a variety of common patterns with ZooKeeper, such as leader election, locks, and so on. The ZooKeeper project site has a decent collection of those patterns (recipes) described here, though there are no specific plans to implement all of them. I will likely experiment with leader election first since this seems to be a very common pattern.

Unlikely to ever get around to this work.
