function state = gaplotstopping(options,state,flag)
%GAPLOTSTOPPING Display stopping criteria levels.
%   STATE = GAPLOTSTOPPING(OPTIONS,STATE,FLAG) plots the current percentage
%   of the various criteria for stopping.  
%
%   Example:
%    Create an options structure that uses GAPLOTSTOPPING
%    as the plot function
%      options = gaoptimset('PlotFcns',@gaplotstopping);
