ROI Token

ROIToken (#421-663) contract sets array length with a user-controlled value:
- lockList[_receiver].push(item) (#544)
Do not allow array lengths to be set directly set; instead, opt to add values as needed. Otherwise, thoroughly review the contract to ensure a user-controlled variable cannot reach an array length assignment.

- ROIToken.fallback() (#583-585)
But does not have a function to withdraw the ether

ROIToken.getLockedAmount(address) (#554-563) uses timestamp for comparisons
Dangerous comparisons:
- now < lockList[lockedAddress][j].releaseDate (#557)
Avoid relying on block.timestamp.
