Description:

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.)

Class protocol:

 isAbstract

Return if this class is an abstract class.
True is returned here for myself only; false for subclasses.
Abstract subclasses must redefine this again.

 isHeadless

this is invoked early by Smalltalk>>mainStartup, to ask if I like to
have a Display or if I am a non-GUI headless application
