/**
 * @public
 * Generate a `TRANSFER` transaction holding the `asset`, `metadata`, and `outputs`, that fulfills
 * the `fulfilledOutputs` of `unspentTransaction`.
 * @param {object} unspentTransaction Previous Transaction you have control over (i.e. can fulfill
 *                                    its Output Condition)
 * @param {object} metadata Metadata for the Transaction
 * @param {object[]} outputs Array of Output objects to add to the Transaction.
 *                           Think of these as the recipients of the asset after the transaction.
 *                           For `TRANSFER` Transactions, this should usually just be a list of
 *                           Outputs wrapping Ed25519 Conditions generated from the public keys of
 *                           the recipients.
 * @param {...number} fulfilledOutputs Indices of the Outputs in `unspentTransaction` that this
 *                                     Transaction fulfills.
 *                                     Note that the public keys listed in the fulfilled Outputs
 *                                     must be used (and in the same order) to sign the Transaction
 *                                     (`signTransaction()`).
 * @returns {object} Unsigned transaction -- make sure to call signTransaction() on it before
 *                   sending it off!
