 rate_stream::get_errors
        Return the error limits of a rate stream.

 Usage:
        error=strref -> get_errors([/upper, /lower])

 Keywords:
        upper                   If set, then return the upper bound errors.
        lower                   If set, then return the lower bound errors.
        delta                   Return the size of the errors.
        times   double  OUTPUT  A named variable in which to return
                                the times of the error bars.
 Notes:
        If no keys are set, then the pointers to the errors are
        returned. N.B. For whatever reason, the errors are stored as
        flux + error and flux - error.
        If the stream doesn't have errors, then 0 is returned.
        For streams where the real cadence is below the data rate, the
        Delta errors are remapped to the data rate unless the TIMES
        keyword is given.

        Add delta keyword and make interface consistent with spect:

        Add times keyword: 8/2/02; SJT
