Notes


      Notes: The info is from the text file named data_set_key.txt
      which must be located in the users home directory.
      Layout of data_set_key.txt:
      Comments (* as first character) and null lines are allowed.
      For each key must have one line:
          key_dataset = value
      Example: etopo1_dataset = /elevation/etopo1_ice_c.res
      May also have any number (0 or more) of lines:
          key_tag1 = line 1
          key_tag1 = line 2
          . . .
      For example:
          key_notes = line 1
          key_notes = line 2
          . . .
      May have lines prefixed by key_ as needed, like
          ybs_mag = m1
          ybs_mag = m2
          . . .
      Use the key 'ybs' to access all the ybs_* lines.
      The key_ is dropped in the returned structure, so the
      main value will always by under the tag s.datatset.
      It is useful to have one or more description comments in
      front of the dataset and notes lines.
