   * https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
   * to implement supply mechanisms].

   * 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}
   * functions have been added to mitigate the well-known issues around setting
   * allowances. See {IERC20-approve}.
