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)".
