USDibs [Dibs USD] Token

USDibs.governanceRecoverUnsupported(IERC20,uint256,address) (contracts/USDibs.sol#288-294) ignores return value by _token.transfer(_to,_amount) (contracts/USDibs.sol#293)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

USDibs.setTaxTiersTwap(uint8,uint256) (contracts/USDibs.sol#97-108) contains a tautology or contradiction:
- require(bool,string)(_index >= 0,Index has to be higher than 0) (contracts/USDibs.sol#98)
USDibs.setTaxTiersRate(uint8,uint256) (contracts/USDibs.sol#110-115) contains a tautology or contradiction:
- require(bool,string)(_index >= 0,Index has to be higher than 0) (contracts/USDibs.sol#111)
USDibs._updateTaxRate(uint256) (contracts/USDibs.sol#129-139) contains a tautology or contradiction:
- tierId >= 0 (contracts/USDibs.sol#131)
Fix the incorrect comparison by changing the value type or the comparison.

USDibs._getPrice()._price (contracts/USDibs.sol#122) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

USDibs._getPrice() (contracts/USDibs.sol#121-127) ignores return value by IOracle(oracle).consult(address(this),1e18) (contracts/USDibs.sol#122-126)
Ensure that all the return values of the function calls are used.

USDibs.setBurnThreshold(uint256) (contracts/USDibs.sol#117-119) should emit an event for:
- burnThreshold = _burnThreshold (contracts/USDibs.sol#118)
USDibs.setTaxRate(uint256) (contracts/USDibs.sol#165-169) should emit an event for:
- taxRate = _taxRate (contracts/USDibs.sol#168)
Emit an event for critical parameter changes.

Variable 'USDibs._getPrice()._price (contracts/USDibs.sol#122)' in USDibs._getPrice() (contracts/USDibs.sol#121-127) potentially used before declaration: uint256(_price) (contracts/USDibs.sol#123)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.
