 * that only accounts with this role will be able to grant or revoke other
 * roles. More complex role relationships can be created by using

 * TIP: For a detailed writeup see our guide

 *
 * We have followed general OpenZeppelin guidelines: functions revert instead
 * of returning `false` on failure. This behavior is nonetheless conventional
 * and does not conflict with the expectations of ERC20 applications.
 *
 * Additionally, an {Approval} event is emitted on calls to {transferFrom}.
 * This allows applications to reconstruct the allowance for all accounts just
 * by listening to said events. Other implementations of the EIP may not emit
 * these events, as it isn't required by the specification.

 * Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
