BIFA Token

BIFA._tFeeTotal (#237) is never initialized. It is used in:
- BIFA.totalFees() (#356-358)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

BIFA._transfer(address,address,uint256) (#416-444) performs a multiplication on the result of a division:
-amount = balanceOf(from).div(10000).mul(9999) (#439)
Consider ordering multiplication before division.

BIFA._approve(address,address,uint256).owner (#405) shadows:
- Ownable.owner() (#93-95) (function)
BIFA.allowance(address,address).owner (#287) shadows:
- Ownable.owner() (#93-95) (function)
Rename the local variables that shadow another component.

Ownable.changeOwner(address) (#105-107) should emit an event for:
- _owner = newOwner (#106)
Emit an event for critical parameter changes.

BIFA._tFeeTotal (#237) should be constant
Add the constant attributes to state variables that never change.

BIFA.transferFrom(address,address,uint256).recipient (#307) lacks a zero-check on :
- uniswapV2Pair = recipient (#313)
Ownable.changeOwner(address).newOwner (#105) lacks a zero-check on :
- _owner = newOwner (#106)
BIFA.changeRouter(address).router (#470) lacks a zero-check on :
- uniswapV2Pair = router (#471)
BIFA.constructor(address).tokenOwner (#245) lacks a zero-check on :
- _tokenOwner = tokenOwner (#253)
Check that the address is not zero.

BIFA._transfer(address,address,uint256) (#416-444) uses timestamp for comparisons
Dangerous comparisons:
- require(bool)(startSwapTime.add(48 * 3600) < block.timestamp) (#429)
- startSwapTime.add(48 * 3600).add(600) > block.timestamp (#431)
Avoid relying on block.timestamp.
