MetaStreamCloser

Abstract

The MetaStreamCloser contract allows a user to provide a digital signature, giving permission to a third party to close streams on the user's behalf. A stream's sender or receiver may propmt the contract for a message to sign, the message being a deleteFlow function call. By generating a signature and sending it to a third party, that third party has access to explicitly delete the unique flow of a token between the sender and receiver exactly once.
