/**	KScribbleDoc provides a document object for a document-view model.
  *
  * The KScribbleDoc class provides a document object that can be used in conjunction with the classes JavaApiTestApp and KScribbleView
  * to create a document-view model for standard KDE applications based on KApplication and KMainWindow. Thereby, the document object
  * is created by the JavaApiTestApp instance and contains the document structure with the according methods for manipulation of the document
  * data by KScribbleView objects. Also, KScribbleDoc contains the methods for serialization of the document data from and to files.
