Supported Models

1. ACL (Access Control List)
2. ACL with superuser
3. ACL without users: This is especially useful for systems that don't have authentication or user logins.
4. ACL without resources: In some scenarios, the target is a type of resource instead of an individual resource. Permissions like "write-article" and "read-log" can be used. This doesn't control access to a specific article or log.
5. RBAC (Role-Based Access Control)
6. RBAC with resource roles: Both users and resources can have roles (or groups) at the same time.
7. RBAC with domains/tenants: Users can have different sets of roles for different domains/tenants.
8. ABAC (Attribute-Based Access Control): Syntax sugar like "resource.Owner" can be used to get the attribute for a resource.
9. RESTful: Supports paths like "/res/*", "/res/:id", and HTTP methods like "GET", "POST", "PUT", "DELETE".
10. Deny-override: Both allow and deny authorizations are supported, where deny overrides allow.
11. Priority: The policy rules can be prioritized, similar to firewall rules.
