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