docs: def get(self, attri, fname=None, numtype='cycNum', decayed=False):
          '''
          In this method all data for an entire cycle (basically the
          content of an iso_massfnnnn.DAT file) or a column of data for
          the associated attribute is returned.
  
          Parameters
          ----------
          attri : string or integer
              If attri is a string, attri is the cycle or name of the
              attribute we are looking for.
  
              If attri is an integer, attri is the cycle number (cycle arrays
              are not supported).
          fname : string, optional
              If attri is a string, fname is the name of the file we are
              getting the data from or the cycle number found in the
              filename, or a List of either cycles or filenames.  If fname
              is None, the data from all cycles is returned.
  
              If attri is an integer, then fname is not supported.
  
              The default is None.
          numtype : string, optional
              If attri is a string, numtype determines whether fname is
              the name of a file or, the cycle number.  If numtype is
              'file' it will then  interpret fname as a file.  If numtype
              is 'cycNum' it will then interpret fname as a cycle number.
  
              If attri is an Integer, then numtype is not supported.
  
              The default is "cycNum".
          decayed : boolean, optional
              If attri is a string, then decayed is not supported.
  
              If attri is an integer, then get instantaneously decay
              abundance distribution.
  
              The default is False.
  
          Returns
          -------
          array
              If attri is a string, data in the form of a numpy array is
              returned.
  
              If attri is an integer, Nothing is returned.
  
          Notes
          -----
          If attri is an integer, then the following variables will be
          added to the instance.
  
          a_iso_to_plot: mass number of plotted range of species.
  
          isotope_to_plot: corresponding list of isotopes.
  
          z_iso_to_plot: corresponding charge numbers.
  
          el_iso_to_plot: corresponding element names.
  
          abunds: corresponding abundances.
  
          isom: list of isomers with their abundances.
