Added reverse map from information space to triangle; moved info coors to transmat window.

% mt_resample - Sample or resample melody triangle transition matrices of given size

%    natural    ~'size of transition matrices to resample'
% -> action mt_system.

% A new set of transition matrices will be sampled and a 3D information space
% scatter plot generated in the figure determined by the initial call to
