  * For the implementation in this example, we have made the following decisions:
  * 1) The script will choose the account sequence and LastLedgerSequence numbers automatically. We allow ripple-lib to choose the fee.
  *    Payments are defined upfront, and idempotency is not needed. If the script is run a second time, duplicate payments will result.
