Exchange

This is a smart contract to expand KIP7 that is created with every liquidity pair. The Factory deploys this as new pool creation is requested. Although the Factory actually stores the two tokens of a pair and swapping takes place through it, the Exchange Contract must be called for liquidity to be provided or taken.
