% To plot the trajectory:
% 1) Extract the mutual information using getinfs, which calls
%    getinf, which performs numerical integration using the histogram
% 2) Stack the information up correctly according to the iteration number
%    using buildexit
% 3) Plot the corresponding information with dotrajectory
%
% Putting all this together, for the data BtoCDataFile and CtoBDatafile,
% the command is
% dotrajectory(buildexit(getinfs(CtoBDataFile),getinfs(BtoCDataFile)),'r')
