Introduction
============

Integrates the FOS/UserBundle in the Sonata Admin Project

 - AdminBundle: add user and group management
 - EasyExtends: allows to generate Application level model

The roles to be assigned to users is split in 2 parts:

 - **editable :** the roles the current user is allowed to assign to other users 
    (permission or role ``MASTER``)
 - **readonly :** the roles assigned to the current user, however the current 
    user is only allowed to see them

When using ACL, the UserBundle prevents ``normal`` user to change settings of 
``super-admin`` users.
