% eeg_retrieve() - Retrieve an EEG dataset from the variable
%                  containing all datasets (standard:ALLEEG).
%
% Usage: >> EEG = eeg_retrieve( ALLEEG, index );
%
% Inputs:
%   ALLEEG     - variable containing all datasets
%   index      - index of the dataset to retrieve
%
% Outputs:
%   EEG        - output dataset. The global variable EEG is also updated 
%
% Note: at this point the function only performs >> EEG = ALLEEG(index);
