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