module that allows children to implement role-based access control mechanisms. Roles are referred to by their `bytes32` identifier. These should be exposed in the external API and be unique. The best way to achieve this is by using `public constant` hash digests: ``` bytes32 public constant MY_ROLE = keccak256(\\\"MY_ROLE\\\"); ``` Roles can be used to represent a set of permissions. To restrict access to a function call, use {hasRole}: ``` function foo() public { require(hasRole(MY_ROLE, msg.sender)); ... } ``` Roles can be granted and revoked dynamically via the {grantRole} and {revokeRole} functions. Each role has an associated admin role, and only accounts that have a role's admin role can call {grantRole} and {revokeRole}. By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means that only accounts with this role will be able to grant or revoke other roles. More complex role relationships can be created by using {_setRoleAdmin}. WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to grant and revoke this role.
