/**	KBaseDoc provides a document object for a document-view model.
  *
  * The KBaseDoc class provides a document object that can be used in conjunction with the classes JavaApiTestApp and KBaseView
  * 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 KBaseView objects. Also, KBaseDoc contains the methods for serialization of the document data from and to files.
