> SystemConsumers multiplexes the register with offset calls to each SystemConsumer. The basic logic that is needed in register() is
> {noformat}
> if there is a startpoint for the SSP and the SystemConsumer implements StartpointVisitor
>     call Startpoint#apply(SSP, StartpointVisitor)
> else
>     call SystemConsumer#register(SSP, checkpointOffset:String){noformat}
> Part of this is to also investigate how startpoints affects the MessageChooser logic.
