   +----semper.util.bootstrap.ApplicationsMenu

public class ApplicationsMenu
extends Object
implements MenuHandler

This class provides a standard way of registering "special" applications (e.g. purse management) to be launched via a pull down menu on the Tinguin. In order to be launchable from this menu, the following steps are necessary:

the application should be implemented in the "launch" method of a class implementing the MenuLaunchable interface,
an object of this class and a menu label must be registered using the "register" method of this class during the bootstrapping process of SEMPER.

At the end of Library#init, a pull down menu with the applications registered so far will be installed on Tinguin.
