swapExactTokensForTokens

function swapExactTokensForTokens(
    uint256 _amountIn, 
    uint256 _amountOutMin, 
    address[] _tokenInOut, 
    address _to, 
    uint256 _deadline, 
    bytes[] _priceUpdateData
) external payable returns (uint256[] amounts_)

Swap some _fromToken tokens for _toToken tokens, ensures _amountOutMin and _deadline, sends funds to _to address msg.sender needs to grant the router contract a sufficient allowance beforehand

By calling this function the price feed gets be updated (IPriceOracleAdapter.updatePriceFeeds)

    uint256 _amountIn, 
    address[] _tokenInOut, 
    uint256[] _tokenPrices
) external view returns (uint256 amountOut_, uint256 swapFee_)

Get a quote for how many _toToken tokens _amountIn many tokenIn tokens can currently be swapped for.
