|
|
* @dev NOTE: RBACWithAdmin is probably too expansive and powerful for your
|
|
* @dev application; an admin is actually able to change any address to any role
|
|
* @dev which is a very large API surface. It's recommended that you follow a strategy
|
|
* @dev of strictly defining the abilities of your roles
|
|
* @dev and the API-surface of your contract.
|
|
* @dev This is just an example for example's sake.
