Implement a simple AMM swap (0% fee ratio) contract in contracts/SimpleSwap.sol. You must override all the external functions of ISimpleSwap.sol, and pass all the tests in test/SimpleSwap.spec.ts.
Suggest reading the natSpec of ISimpleSwap.sol first and then implementing the contract. If you are not sure what the function is about, feel free to discuss it in the Discord channel.
