     *
     * By default, roles have `adminRole` of `0x00` (since the storage is just empty). This is

     * `DEFAULT_ADMIN_ROLE` to one address which can then distribute required roles. If we

     * recursive logic to support the same business logic in more scalable fashion.
     *
     * Having the admin be able to manage roles is usually good but we have a problem however.
     * How can we assign roles and freeze them, making sure that no one can re-assign the role
     * to other addresses? Only two solutions are possible:
     * 1. Renouce the `DEFAULT_ADMIN_ROLE`
     * 2. Add a `NULL_ROLE`, make it never assignable, and set that as the roles new `adminRole`
     *
     * Solution 1 is the simplest, but has the main drawback that by relinquishing the
     * `DEFAULT_ADMIN_ROLE` (forever), we lose the flexibility of being able to assign new roles,
     * especially roles with new identifiers.
