// New Transaction: key --
// We create a new transaction, and track it with the user supplied key. The
// user can then use this key to make subsequent calls to add inputs, outputs,
// and to sign. Then they can submit the transaction.
//
// When the transaction is submitted, we clear it from our working memory.
// Multiple transactions can be under construction at one time, but they need
// their own keys. Once a transaction is either submitted or deleted, the key
// can be reused.
