/**
* A simple text editor. This application implements a very simple
* mapping between view and documents. There is only one view.
* Documents that are not currently being viewed are hidden and not available
* until the currently viewed document is closed. When a new document
* is to be viewed, the single view is associated with that document and
* its contents updated.
* <p>
* This kind of architecture is enough for simple applications that contain
* few documents (or more likely, only one document). For applications
* that require simultaneous editing of several documents, an MDI interface
* makes more sense. See MDIApplicationTutorial for an instance of the
* same application implemented in an MDI style.
