%                          Fields covered: filename, subject, condition,
%                          group, session, run.

% Usage:
%   >> [STUDY, ALLEEG] = pop_checkdatasetinfo(STUDY, ALLEEG);
%                                              
% Inputs:
%   STUDY      - STUDY structure
%
%   ALLEEG     - array of all EEG dataset in STUDY
% Outputs:
%   STUDY      - If there's inconsistency and user select to copy info,
%                returned STUDY contains the missing info copied from
