HUAJIAN Token

HUAJIAN.maxTXEnabled (#195) is never initialized. It is used in:
- HUAJIAN.tokenTransfer(address,address,uint256) (#273-287)
HUAJIAN.checkVotes (#208) is never initialized. It is used in:
- HUAJIAN.getbonus(address) (#391-394)
HUAJIAN.numCheckVotes (#209) is never initialized. It is used in:
- HUAJIAN.getbonus(address) (#391-394)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

HUAJIAN.selltoken(uint256,uint256) (#396-402) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#397)
- block.timestamp - lastClaimTime >= claimWait (#401)
Avoid relying on block.timestamp.

HUAJIAN._maxTxAmount (#207) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 10
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
