// A simple contract that helps to understand what _data should be attached to a token transaction
// in order to make it call specific values amountIn, amountOutMin, path, to, deadline
// in the SoyFinance exchange contract.

// You can simply fill args for the `get_erc223_calldata()` function in the deployed contract
// then take whatever it returns and assign to `_data` arg of the `transfer(address, uint256, bytes calldata)` function of ERC223 token
// in order to make it call this exactly `swapExactERC223ForTokens()` with given args upon being handled inside of `tokenReceived` fallback
// at the SouFinanceRouter contract.
