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