%| GUIDE automatically appends subfunction prototypes to this file, and 
%| sets objects' callback properties to call them through the FEVAL 
%| switchyard above. This comment describes that mechanism.
%| Each callback subfunction declaration has the following form:
%| The subfunction name is composed using the object's Tag and the 
%| callback type separated by '_', e.g. 'slider2_Callback',
%| 'figure1_CloseRequestFcn', 'axis1_ButtondownFcn'.
%| H is the callback object's handle (obtained using GCBO).
%| EVENTDATA is empty, but reserved for future use.
%| HANDLES is a structure containing handles of components in GUI using
%| tags as fieldnames, e.g. handles.figure1, handles.slider2. This
%| structure is created at GUI startup using GUIHANDLES and stored in
%| the figure's application data using GUIDATA. A copy of the structure
%| is passed to each callback.  You can store additional information in
%| this structure at GUI startup, and you can change the structure
%| during callbacks.  Call guidata(h, handles) after changing your
%| copy to replace the stored original so that subsequent callbacks see
%| the updates. Type "help guihandles" and "help guidata" for more
%| information.
%| VARARGIN contains any extra arguments you have passed to the
%| callback. Specify the extra arguments by editing the callback
%| property in the inspector. By default, GUIDE sets the property to:
%| <MFILENAME>('<SUBFUNCTION_NAME>', gcbo, [], guidata(gcbo))
%| Add any extra arguments after the last argument, before the final
%| closing parenthesis.

% Obtaining the Figure Handle from Within a Callback.   In general, dismissing a modal figure requires the handle
% of the figure. Since most GUIs hide figure handles to prevent accidental access, the gcbf (get callback figure)
% command provides the most effective method to get the figure handle from within a callback routine.
% gcbf returns the handle of the figure containing the object whose callback is executing. This enables you to use
% gcbf in the callback of the component that will dismiss the dialog. For example, suppose your dialog includes a
% push button (tagged pushbutton1) that closes the dialog. Its callback could include a call to delete at the end of
% its callback subfunction.
