This will allow BankClient to spin up a thread to use the Bank.
It'll also ease the transaction from BankClient to ThinClient since
it won't let you depend on Bank.
Drawback, you the transition from Bank to BankClient will be harder
because the Bank methods are inaccessible.
This module predates Accounts. That was a separate module because
it used to be part of Bank and those types could be sent to any
smart contract. Now each instruction processor defines for itself
what instructions it accepts.
