%GUIDE M-file for guide.fig
%      GUIDE, by itself, creates a new GUIDE or raises the existing
%      singleton*.
%
%      H = GUIDE returns the handle to a new GUIDE or the handle to
%      the existing singleton*.
%
%      GUIDE('Property','Value',...) creates a new GUIDE using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to guide_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      GUIDE('CALLBACK') and GUIDE('CALLBACK',hObject,...) call the
%      local function named CALLBACK in GUIDE.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
