    When smalltalk is started as IDE (stx), the show starts in Smalltalk>>start.
    In contrast, when a standAlone app is linked, 
    the show starts in the startup class's start method.

    This class is an abstract, subclassable template for a standalone headless-application's startup.
    For your own stand alone programs, define a subclass of this, 
    and redefine the #main: method there.
    (of course, the other methods can also be redefined.)
