getOrderAmounts(uint256[] _orderIds, uint256 amountToFill, uint256 maxSpend) -> uint256[], uint256
Returns the amount of the asset to be filled from each order in _orderIds. The sum of which cannot exceed amountToFill, and the cumulative price cannot exceed maxSpend.

getPaymentTotals(uint256[] _orderIds, uint256[] _amounts) -> uint256, uint256[]
Returns the token payment to be paid for each order in orderIds and the cumulative payment for the entire fill order.
