/**
* {@link Beta} <br/>
* Thread-safe Webhook App Engine Servlet to receive notifications.
*
* <p>
* In order to use this servlet you need to register the servlet in your web.xml. You may optionally
* extend {@link AppEngineNotificationServlet} with custom behavior.
* </p>
*
* <p>
* It is a simple wrapper around {@link WebhookUtils#processWebhookNotification(HttpServletRequest,
* HttpServletResponse, DataStoreFactory)} that uses
* {@link AppEngineDataStoreFactory#getDefaultInstance()}, so you may alternatively call that method
* instead from your {@link HttpServlet#doPost} with no loss of functionality.
* </p>
*
* <b>Sample web.xml setup:</b>
*
* <pre>
