FlexAtom.addLiquidity(uint256,uint256) (#1402-1417) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#1408-1415)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

FlexAtom._transfer(address,address,uint256) (#1341-1382) uses a dangerous strict equality:
- CoolDown[to] == 0 (#1353)
FlexAtom._transfer(address,address,uint256) (#1341-1382) uses a dangerous strict equality:
- (block.number.sub(CoolDown[from]) < 2) || (block.number.sub(CoolDown[from]) == 100) (#1365)
Don't use strict equality to determine if an account has enough Ether or tokens.
