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