        """
        Parser that keeps trying to interpret bytes it is fed with as
        incoming frames part of a message.

        Control message are single frames only while data messages, like text
        and binary, may be fragmented accross frames.

        The way it works is by instanciating a :class:`wspy.framing.Frame` object,
        then running its parser generator which yields how much bytes
        it requires to performs its task. The stream parser yields this value
        to its caller and feeds the frame parser.

        When the frame parser raises :exc:`StopIteration`, the stream parser
        tries to make sense of the parsed frame. It dispatches the frame's bytes
        to the most appropriate message type based on the frame's opcode.

        Overall this makes the stream parser totally agonstic to
        the data provider.
