/**
 * @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 using  { 
                        _mint
                        }.
 * For a generic mechanism see {
                        ERC20PresetMinterPauser
                        }.
 *
 * TIP: For a detailed writeup see our guide
 * https://forum.openzeppelin.com/t/how-to-implement-erc20-supply-mechanisms/226[How
 * to implement supply mechanisms].
 *
 * The default value of  { 
                        decimals } 
                         is 18. To change this, you should override
 * this function so it returns a different value.
 *
 * We have followed general OpenZeppelin Contracts guidelines: functions revert
 * instead 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}
                        .
