/*

  This application demonstrates configuration of multiple layout managers and multiple 

  text container/text view pairs on a single text storage.  On the left, it displays a 

  single standard text view, representing a continuous view of e.g. a slide presentation.

  On the right, the same text is displayed with a separate layout manager and a set of

  fixed-size text containers and text views, representing a slide-by-slide view.  For

  demo purposes we present a fixed number of slides; a real application would create

  them dynamically as needed, as for example TextEdit creates pages in wrap-to-page

  mode (see the TextEdit source for details).
