RBAC, file storage and rules container 1.0.0

Three RBAC packages are released in their initial stable version: rbac, rbac-php, and rbac-rules-container.

These packages provide RBAC (Role-Based Access Control) library. They are used in Yii Framework but is usable separately as well. Main features are:

• Flexible RBAC hierarchy with roles, permissions and rules.
• Role inheritance.
• Data could be passed to rules when checking access.
• Multiple storage adapters.
• Separate storages could be used for user-role assignments and role hierarchy.
• API to manage RBAC hierarchy.
• Database storages are in the making.

Overall usage examples are available in the rbac package readme.
