 * A single signed transaction, including all its signatures. The SignatureList will have a

 * appear in the transaction. For example, a CryptoTransfer will first have a Signature
 * corresponding to the Key for the paying account, followed by a Signature corresponding to the Key
 * for each account that is sending or receiving cryptocurrency in the transfer. Each Transaction
 * should not have more than 50 levels. 
 * The SignatureList field is deprecated and succeeded by SignatureMap.
