      INPUT PARAMETERS: 
          TableName:   local table name to fetch in (required)
          iso_id_list: list of isotopologue id's    (required)
          numin:       lower wavenumber bound       (required)

      DESCRIPTION:
          Download line-by-line data from HITRANonline server
          and save it to local table. The input parameter iso_id_list
          contains list of "global" isotopologue Ids (see help on ISO_ID).
          Note: this function is required if user wants to download
          multiple species into single table.

      EXAMPLE OF USAGE:
          fetch_by_ids('water',[1,2,3,4],4000,4100)
