function varargout = tul(varargin)
% TUL MATLAB code for tul.fig
% TUL, by itself, creates a new TUL or raises the existing
% singleton*.
%
% H = TUL returns the handle to a new TUL or the handle to
% the existing singleton*.
%
% TUL('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in TUL.M with the given input arguments.
%
% TUL('Property','Value',...) creates a new TUL or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before tul_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to tul_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
