function concatStructTSG( hMainFig, tsg_old )
%
% Concatenate some elements of a TSG structure. Mainly :
% - TSG data members (DAYD, DATE, LATX, LONX, SSPS, SSJT, SSTP)
% - Discrete data (_EXT) members (DAYD, DATE, LATX, LONX, SSPS, SSTP) 
%
% Right now, the function do not concatenate :
% - Calibration coefficent
% - '_HIST'
% - preference
%
% If the concatenanted TSG structures have identical dates, the double
% are supressed.
%
% This function is called by read_data.m

% The function calls :
% concatNumTsg    - At the end of this file
% concatInt8Tsg   - At the end of this file
% supTsgDouble    - At the end of this file
% supTsgExtDouble - At the end of this file
%
