show_CA_List.m

% plots images from evolution of a CA, all in one figure
%           waiting for user keypress before changing image
% inputs:   list -- list of CA frames to be plotted
%           interval -- every  <interval> frames willbe plotted
%           upperCmapBound -- lowest value for upperbound on colormap
%           lowerCmapBound -- highest value for lower bound on colormap
% outputs: none
% side effects: changes images in a figure window
