/** Receives signals over a given Socket.

    This class is intended to be used in conjuction with SignalSender.

    There are two types of messages,
    layout descriptions and record data.  If a layout description
    is read, internal setup for receiving record of that layout is done.
    If record data is read, and the layout description has been received
    then the record is created and used as a signal to the associated
    signaler.
