          '''
          Method that plots figures and saves those figures to a .png
          file.  Plots a figure for each cycle in the argument cycle.
          Can be called via iso_abund method by passing a list to cycle.
  
          Parameters
          ----------
          cycllist : list
              The cycles of interest.  This method will do a plot for
              each cycle and save them to a file.
          stable : boolean, optional
              A boolean of whether to filter out the unstables.  The
              defaults is False.
          amass_range : list, optional
              A 1x2 array containing the lower and upper atomic mass
              range.  If None plot entire available atomic mass range.
              The default is None.
          mass_range : list, optional
              A 1x2 array containing the lower and upper mass range.  If
              this is an instance of abu_vector this will only plot
              isotopes that have an atominc mass within this range.  This
              will throw an error if this range does not make sense ie
              [45,2].  If None, it will plot over the entire range.  The
              defaults is None.
          ylim : list, optional
              A 1x2 array containing the lower and upper Y limits.  If
              it is [0,0], then ylim will be determined automatically.
              The default is [0,0].
          ref : integer or list, optional
              reference cycle.  If it is not -1, this method will plot
              the abundences of cycle devided by the cycle of the same
              instance given in the ref variable.  If ref is a list it
              will be interpreted to have two elements:
              ref=['dir/of/ref/run',cycle] which uses a refernece cycle
              from another run.  If any abundence in the reference cycle
              is zero, it will replace it with 1e-99.  The default is -1.
          decayed : boolean, optional
              If True plot decayed distributions, else plot life
              distribution.  The default is False.
          include_title : boolean, optional
              Include a title with the plot.  The default is False.
          title : string, optional
              A title to include with the plot.  The default is None.
          pdf : boolean, optional
              Save image as a [pdf/png].  The default is False.
          color_plot : boolean, optional
              Color dots and lines [True/False].  The default is True.
          grid : boolean, optional
              print grid.  The default is False.
          point_set : integer, optional
              Set to 0, 1 or 2 to select one of three point sets, useful
              for multiple abundances or ratios in one plot.  The defalult
              is 1.
