% :param a:
%     Instance of class :mat:func:`Kinetics` (or another
%     object deriving from Kinetics)
%     for which the net rates of progress are desired.
% :return:
%     Returns a column vector of the net rates of progress
%     for all reactions. If this function
%     is called with no output argument, a bar graph is produced.
