-/// This test aims to make sure the PUT validation of nodes are working as expected. We perform valid spends and also

-/// The illicit spends can be of these types:
-/// 1. A double spend of a transaction whose outputs are partially spent / partially UTXO
-/// 2. A double spend of a transcation whose outputs are all UTXO.
-/// 3. Poisoning of a transaction whose outputs are all spent.
-/// Todo: Double spend just 1 input spend. Currently we double spend all the inputs. Have TransactionStatus::DoubleSpentInputs(vec<inputs>)
-///
-/// The test works by having a main loop that sends actions to all the wallets. These are then processed by the wallets
-/// in parallel. The wallets send back the results of the actions to the main loop, this is then tracked and the whole
-/// cycle is repeated until the max cycles are reached.

-//! This module contains the functions for creating an online/offline transfer of tokens.
-//! This is done by emptying the input cash_notes, thereby rendering them spent, and creating
-//! new cash_notes to the recipients (and a change cash_note if any) containing the transferred tokens.
-//! When a transfer is created, it is not yet registered on the network. The signed spends of
-//! the transfer is found in the new cash_notes, and must be uploaded to the network to take effect.
-//! The peers will validate each signed spend they receive, before accepting it.
-//! Once enough peers have accepted all the spends of the transaction, and serve them upon request,
-//! the transfer is completed and globally recognised.
-//!
-//! The transfer is created by selecting from the available input cash_notes, and creating the necessary
-//! spends to do so. The input cash_notes are selected by the user, and the spends are created by this
-//! module. The user can select the input cash_notes by specifying the amount of tokens they want to
-//! transfer, and the module will select the necessary cash_notes to transfer that amount. The user can
-//! also specify the amount of tokens they want to transfer to each recipient, and the module will
-//! select the necessary cash_notes to transfer that amount to each recipient.
-//!
-//! On the difference between a transfer and a transaction.
-//! The difference is subtle, but very much there. A transfer is a higher level concept, it is the
-//! sending of tokens from one address to another. Or many.
-//! A cash_note transaction is the lower layer concept where the blinded inputs and outputs are specified.
