List of things to discuss
=========================
Relation between zena, custom applications and bricks:
1. custom models
2. custom migrations
3. custom zafu rules
4. custom tests
Folder structure should be like a rails application with some elements missing (all zena controllers, views, helpers, etc). It
should still launch in Passenger and all other servers like mongrel.
