Permissionable

The Permissionable component is primarily used to set permissions for authorized addresses to carry out specific actions.

By leveraging this component, developers can build applications where users maintain control over key functions while safely delegating specific tasks to other addresses. Permissioned addresses can also play a minimal role of guardians.

The full contract code of the PermissionableComponent can be found here.
