##Sketch for Enliven Component Model

This design page is a sketch of how I see enliven being used for dynamic templates in the browser.

Design Principles

1. All state is in an application state object.
2. State is scoped through lenses.
3. Users should not have to manage lenses manually.
4. There is no tree walking; paths/lenses, for dom manipulation, are determined at compile time.
