XMS [Mars Ecosystem] Token

XMSToken._writeCheckpoint(address,uint32,uint96,uint96) (contracts/base/XMSToken.sol#463-489) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/base/XMSToken.sol#476-477)
Don't use strict equality to determine if an account has enough Ether or tokens.

CoreRef.getUSDMAmountGovernance().j (contracts/refs/CoreRef.sol#167) is a local variable never initialized
CoreRef.getUSDMAmountGovernance().i (contracts/refs/CoreRef.sol#165) 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.

XMSToken.permit(address,address,uint256,uint256,uint256,uint8,bytes32,bytes32) (contracts/base/XMSToken.sol#136-194) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= expiry,XMSToken::permit: Signature expired) (contracts/base/XMSToken.sol#187-190)
XMSToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/base/XMSToken.sol#277-319) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= expiry,XMSToken::delegateBySig: Signature expired) (contracts/base/XMSToken.sol#314-317)
Avoid relying on block.timestamp.
