CDZ [CDzExchange] Token

CDzToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/CDzToken.sol#218-236) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/CDzToken.sol#228)
Don't use strict equality to determine if an account has enough Ether or tokens.

CDzToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/CDzToken.sol#84-125) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= expiry,CDZ::delegateBySig: signature expired) (contracts/CDzToken.sol#123)
Avoid relying on block.timestamp.
