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

% This function has no output args, see OutputFcn.
