 /**

  * This code is taken from the tutorial written by Jörn Hameister, <A

  * HREF="http://www.hameister.org/JavaSwingTreeTable.html">available here</A>.<BR/>

  * <BR/>

  * From Jörn sample, the main modifications are:

  * <UL>

  * <LI>Add of an even Listener, to report data modifications to the table.</LI>

  * <UL>

  * <BR/>

  * Since Java Swing GUI components also still needed a model that actually is not equal to the data model, is now a

  * class MyTreeTableModelAdapter which of AbstractTableModel inherits created. This class will be later in the class

  * MyTreeTable as a model for the JTable uses. If the TreeTable later for values ​​asks to be displayed, it must be

  * determined whether the requested values ​​of the tree or directly from the data model

  * MyAbstractTreeTableModel<MyHierarchicalNode> can be delivered. In addition, in the class, nor is

  * TreeExpansionListener created and registered. This responds to clicks in the tree and makes dafüf that the tree is up

  * and closed.
