ICO Generator Features
Let's walk through the features ICO Generator provides. First of all, some sections of the code are not possible to remove, as they are always required, no mater what features you select.

Safe Math
A small helper class, taking care of arithmetic overflow errors. Let's say you have a balance variable, and it is equal to 10. Then you (accidentally) subtract 20 from it. As Solidity does not have negative numbers, an overflow happens, and now the "balance" holde a REALLY large number. Which can create a disaster, as we are talking about money. SafeMath makes this situation impossible.
