SAFEGAS Token

SafeGas._tFeeTotal (#91) is never initialized. It is used in:
- SafeGas.totalFees() (#183-185)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

SafeGas.totalSupply (#87) shadows:
- ERC20Basic.totalSupply (#58)
Remove the state variable shadowing.

SafeGas.getTokens() (#220-277) performs a multiplication on the result of a division:

Consider ordering multiplication before division.

SafeGas.getTokens() (#220-277) uses timestamp for comparisons
Dangerous comparisons:
- msg.value >= requestMinimum && now < deadline && now < round1 && now < round2 (#231)
- msg.value >= requestMinimum && now < deadline && now > round1 && now < round2 (#239)
- now >= deadline && now >= round1 && now < round2 (#261)
Avoid relying on block.timestamp.

SafeGas.getTokens() (#220-277) compares to a boolean constant:
-Claimed[investor] == false && progress0drop <= target0drop (#253)
Remove the equality to the boolean constant.

SafeGas.Distribute(address,uint256) (#187-201) has costly operations inside a loop:
- totalDistributed = totalDistributed.add(_amount) (#192)
SafeGas.Distribute(address,uint256) (#187-201) has costly operations inside a loop:
- distributionFinished = true (#195)
Use a local variable to hold the loop computation result.

SafeGas.calculateLiquidityFee(uint256) (#156-160) is never used and should be removed

SafeGas._previousTaxFee (#93) is set pre-construction with a non-constant function or state variable:
- _taxFee
SafeGas._previousLiquidityFee (#95) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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.

Pragma version^0.4.26 (#5) allows old versions
solc-0.4.26 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
