original_docstring: 
      Parse the sting specifying selected species to the list of tuples in the
      form (atomic_number, ion_number).
  
      Parameters
      ----------
      species: str
          Sting that specifies selected species. It should consist of semicolon-separated entries.
          The entries can be just element symbols or ranges of elements symbols. In this case
          all ions of the elements are selected. Also, ion numbers (starting from 0)
          can be specified - either as numbers or ranges. In this case only ions that have
          the corresponding ionization stage are selected.
  
      Returns
      -------
      list of tuples (atomic_number, ion_number)
          List of selected ions
  
      Examples
      --------
  
      >>> parse_selected_species('H')
      [(1, 0)]
  
      >>> parse_selected_species('H-Li')
      [(1, 0), (2, 0), (2, 1), (3, 0), (3, 1), (3, 2)]
  
      >>> parse_selected_species('h-li 0')
      [(1, 0), (2, 0), (3, 0)]
  
      >>> parse_selected_species('b 3-5')

      >>> parse_selected_species('Li 3; B-O 4-5')
      [(5, 4), (6, 4), (6, 5), (7, 4), (7, 5), (8, 4), (8, 5)]
  
      
docstring: Parse the sting specifying selected species to the list of tuples in the
  form (atomic_number, ion_number).
  
  Parameters

  all ions of the elements are selected. Also, ion numbers (starting from 0)
  can be specified - either as numbers or ranges. In this case only ions that have
  the corresponding ionization stage are selected.
  
  Returns

  List of selected ions
