/**
 * Ensures that user is authenticated in session. If no user is signed in, a sign in is forced by
 * redirecting the browser to the SignIn page.
 * <p>
 * This base class also creates a border for each page subclass, automatically adding children of
 * the page to the border. This accomplishes two important things: (1) subclasses do not have to
 * repeat the code to create the border navigation and (2) since subclasses do not repeat this code,
 * they are not hardwired to page navigation structure details
