function varargout = maingui(varargin)
% MAINGUI M-file for maingui.fig
% MAINGUI, by itself, creates a new MAINGUI or raises the existing
% singleton*.
%
% H = MAINGUI returns the handle to a new MAINGUI or the handle to
% the existing singleton*.
%
% MAINGUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MAINGUI.M with the given input arguments.
%
% MAINGUI('Property','Value',...) creates a new MAINGUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before maingui_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to maingui_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
