CARBO [CLEANCARBON] Token

RecoverableFunds.retrieveTokens(address,address) (contracts/RecoverableFunds.sol#13-16) ignores return value by token.transfer(recipient,token.balanceOf(address(this))) (contracts/RecoverableFunds.sol#15)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.
