%      LIST_1, by itself, creates a new LIST_1 or raises the existing

%      singleton*.

%

%      H = LIST_1 returns the handle to a new LIST_1 or the handle to

%      the existing singleton*.

%

%      LIST_1('CALLBACK',hObject,eventData,handles,...) calls the local

%      function named CALLBACK in LIST_1.M with the given input arguments.

%

%      LIST_1('Property','Value',...) creates a new LIST_1 or raises the

%      existing singleton*.  Starting from the left, property value pairs are

%      applied to the GUI before list_1_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

%      stop.  All inputs are passed to list_1_OpeningFcn via varargin.
