 Convenience package for swapping assets represented on the Ethereum blockchain using 0x. The package helps to perform all the off-chain computations to execute a marketBuy or marketSell function execution with 0x exchange contracts, or 0x extension contracts. Given some liquidity (0x signed orders), it helps estimate the cost of buying or selling a certain asset (giving a range) and then provide varying consumable outputs to execute the buy or sell.
