Navigation implements a design pattern that allows you to navigate through complex systems by means of "navigation chains". Each node in the navigation chain is represented as its own object, and can have any number of child links attached to it (done through upwards linking; navigations have no knowledge of their children). This means that you can create a navigation chain to a common point in your system, and then attach multiple subchains at that point. The proof-of-concept handles most HTML navigation requirements, and is used by the author to test Web applications.
