% Initialisation der GUI
% ----------------------

% figure_handle und axis_handle setzen
% aktuelle Achse in Figure figure_handle finden
% axis_handle=get(figure_handle,'CurrentAxes');
% Benutzerdaten userdata der Figure figure_handle auslesen

%	Create a field "first_contour" to create defaults the first time 
%       the menu item is selected

%	Use axis mnemonices in GUI
set(figure_handle,'userdata',ud)

%	FIG Datei oeffnen + handles generieren
fid = openfig(mfilename,'reuse');

%	Store handle of menu so that it can be deleted upon termination of the browser
add_handle2delete1(fid,figure_handle)

%	Generate a structure of handles to pass to callbacks, and store it. 
handles = guihandles(fid);

%	Make GUI invisible
