Why no databases documents for rbac

[Ocramius]

This module provides no DB integration - DB integration is to be implemented by implementing a custom https://github.com/zendframework/zend-permissions-rbac/blob/98252acae03f52e83e937150efe81f621e15891c/src/Rbac.php that reads from the DB instead of performing in-memory operations.
