/**
* @dev Contract module that allows children to implement role-based access

*
* Roles are referred to by their `bytes32` identifier. These should be exposed

*
* ```
* bytes32 public constant MY_ROLE = keccak256("MY_ROLE");

*

* {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}.
*
