}

DirectTransfer is a direct token exchange, used when both participants have a previously opened channel.

Signs the unidirectional settled `balance` of `token` to `recipient` plus locked transfers.

Settled refers to the inclusion of formerly locked amounts. Locked amounts are not included in the balance yet, but represented by the `locksroot`.

Args: 

nonce: A sequential nonce, used to protected against replay attacks and
    to give a total order for the messages. This nonce is per
    participant, not shared.
token: The address of the token being exchanged in the channel.
transferred_amount: The total amount of token that was transferred to
    the channel partner. This value is monotonically increasing and can
    be larger than a channels deposit, since the channels are
    bidirecional.
recipient: The address of the Photon node participating in the channel.
locksroot: The root of a merkle tree which records the current
    outstanding locks.

	Fee            *big.Int
	Path           []common.Address // 2019-03 消息升级后,带全路径信息
}

MediatedTransfer has a `target` address to which a chain of transfers shall be established. Here the `haslock` is mandatory.

`fee` is the remaining fee a recipient shall use to complete the mediated transfer. The recipient can deduct his own fee from the amount and lower `fee` to the remaining fee. Just as the recipient can fail to forward at all, or the assumed amount, it can deduct a too high fee, but this would render completion of the transfer unlikely.

The initiator of a mediated transfer will calculate fees based on the likely fees along the path. Note, it can not determine the path, as it does not know which nodes are available.

Initial `amount` should be expected received amount + fees.

Fees are always payable by the initiator.

`initiator` is the party that knows the secret to the `hashlock`
