Create business classes from the database to have complete scaffold support from the DB

The current version of Grails is Java centric - and this is good and important- so the main component is class, busines class to be exact.

For some developer the database is still the center of the world, and it will be helpful to allow then to generate their application from the existing schema instead of forcing them to create the business class first. This is very close to the current RoR approach.
