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