* Role Based Access Control:
*
* Implement a role based auth system. System should be able to assign a role to user and remove a user from the role.
*
* Entities are USER, ACTION TYPE, RESOURCE, ROLE
*
* ACTION TYPE defines the access level(Ex: READ, WRITE, DELETE)
*
* Access to resources for users are controlled strictly by the role.One user can have multiple roles. Given a user, action type and resource system should be able to tell whether user has access or not.
