documentation
"    
    ActivityNotification can be raised from deeply nested methods, which are going to perform
    some long-time activity.

    If there is a handler for the ActivityNotification, that one is called,
    passing the argument. The handler should show this message whereever it likes,
    and proceed. If there is no handler, ActivityNotification is simply ignored.

    This is very useful to pass busy messages up to some higher level (typically a view)
    which likes to display that message in its label or a busy-box.
    It could also be put into some logfile or printed on the standard output/error.

    It produces an info box with the message on the screen. 
    If no display is available, the message is written 
    to the Transcript.
