 ## Overview
 RZDataBinding is a framework designed to help maintain data integrity in your iOS or OS X app. It is built using the standard Key-Value Observation (KVO) framework, but is safer and provides additional functionality. Like KVO, RZDataBinding helps to avoid endless delegate chains by establishing direct callbacks for when an object changes state.

 **Register a callback for when the keypath of an object changes:**
 ``` obj-c
 // Register a selector to be called on a given target whenever keyPath changes on the receiver.
