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