% Applies descriptor to every cuboid of every clip of every set.
%
% Loads each cuboids_[activity].mat, describues cuboids, then saves result to
% features_[activity].mat.  Each original mat file should contain the fields: 'clipname',
% 'cliptype', 'cuboids', 'subs', resulting mat file will contain the fields:
% 'clipname', 'cliptype', 'subs', 'desc'.
%
% INPUTS
%   nsets       - number of sets
%   cubdesc     - cuboid descriptor
