Currently we have no generic information flows apart from the type and state, everything else is specific to the flow type. Start introducing generic flow information by recording the pifs which the flow connects. To keep track of what information is valid, introduce new flow states: INI for when the initiating side information is complete, and TGT for when both sides information is complete, but we haven't chosen the flow type yet. For now, these states don't do an awful lot, but they'll become more important as we add more generic information.
