/**
* @public
* Generate a `CREATE` transaction holding the `asset`, `metadata`, and `outputs`, to be signed by
* the `issuers`.
* @param {object} asset Created asset's data
* @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 `CREATE` Transactions, this should usually just be a list of
* Outputs wrapping Ed25519 Conditions generated from the issuers' public
* keys (so that the issuers are the recipients of the created asset).
* @param {...string[]} issuers Public key of one or more issuers to the asset being created by this
* Transaction.
* Note: Each of the private keys corresponding to the given public
* keys MUST be used later (and in the same order) when signing the
* Transaction (`signTransaction()`).
* @returns {object} Unsigned transaction -- make sure to call signTransaction() on it before
* sending it off!
