% Converts between representations of behavior (mat -> DATASETS).

% See RECOGNITION_DEMO for general info.
%   [datadir(set_ind)/namei.mat] --> DATASETS
%
% INPUTS
%   nsets       - number of sets
%   cliptypes       - types of clips (cell of strings)
%
% OUTPUTS
%   DATASETS    - array of structs, will have fields:
%           .IS         - the N behavior clips 
%           .IDX        - length N vector of clip types
