Contribution from KALLISTO:

Virtual initialize() method added to application classes in order to enable customization of base app behavior in derived classes.
Example: access from modules auto-loaded by CAM_Application to standard GUI actions created by STD_Application.
It is no longer necessary to redefine start() method, redefining initialize() is a prefereed way to customize application start-up.
