%% Create App with Timer Object Configured Programmatically
% This app shows how to create a timer object in App Designer that executes 
% a function at regular time intervals. In this case, the app queries the 
% available system memory every second and plots the percentage of memory 
% that the system is using.
%
% This example also demonstrates the following app building tasks:
%
% * Writing a callback for an object created programmatically (in this case, the timer object)
% * Configuring a timer object to execute its callback at regular intervals
% * Starting the timer when the user clicks the *Start* button
% * Stopping the timer when the user clicks the *Stop* button
% * Deleting the timer when the app closes
