function varargout = Foot(varargin)

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