 mag_rate_stream::init
        Constructor for a Mag data stream (this will, in
        practice always be called by a wrapper for EPAM or HISCALE).

 Usage:
        strid = obj_new('mag_rate_stream', type, parent, channel, idfref)

 Arguments:
        type    string  The type of stream (this is fixed at the next
                        level up)
        parent  objref  The reference of the dataset to which the
                        stream is attached.
        channel string  The channel that the stream will contain.

 Keywords:
        name    string  A name to attach to the stream.
        menu            If set, then use a menu to define the stream's
                        properties
        group   long    Widget group leader -- only used with menu option.
        system  int     The coordinate system (the actual
                        interpretation depends on whether it's HISCALE
                        or EPAM)
