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