[code423n4]

1. use abi.encodepackage rather than use abi.encode

2. ++i costs less gas tha i++, especially when it's used in for-loops

save 6 gas per loop

3. Consider making some constants as non-public to save gas

Reducing from public to private or internal can save gas when a constant isn’t used outside of its contract. I suggest changing the visibility from public to internal or private.
