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