Enables repoze.bfg to render a website constisting of flexible tiles.

A tile is a piece of web application, i.e. a form, a navigation, etc.

Those HTML-Snippets looked up dynamically using the ZCA.

Splitting your application in such small and logic application parts makes it easy to re-use this application, simplifies application ajaxification and the use of same application parts in different manners.
