/**
 * The purpose of this class is to create a user interface that will
 * provide an intuitive method of building "playlists" of weka 
 * classifiers to be trained.  The main gui consists of two parts: the
 * top and bottom. The top will use a JTree to show all of the options
 * available for a particular classifier. The intent of showing these 
 * options in a tree is to allow users to collapse/expand tree nodes 
 * to quickly access all of the available options at different levels.
 * The bottom half of the gui will show the current "playlist" of 
 * chosen models that the user can opt to add to the current library.  
 * <p/>
 * The overall concept is that users will use the tree to specify 
 * combinations of options to the currently selected classifier type.
 * then they will use the "generate models" button to generate a set
 * models from the selected options. This can be done many times with
 * different sets of options for different model types to generate a
 * list in the bottom half of the gui.  Once the user is satisfied
 * with their list of models they are provided a button to "add all 
 * models" to the model library displayed by the ListModelsPanel.
 * <p/>
 * Note that there are currently 9 different classes that implement
 * tree nodes and tree node editors created to support this class
 * in modelling/rendering weka classifier parameters. see 
 * appropriate classes for details.  They currently reside in the 
 * weka.gui.libraryEditor.tree package.
 * <p/>
 * To instantiate the treeModel:
 * <ul>
 *   <li>ModelNodeEditor</li>
 *   <li>ModelNodeRenderer</li>
 * </ul>
 * 
 * To render/model weka objects:
 * <ul>
 *   <li>PropertyNode</li>
 *   <li>GenericObjectNode</li>
 *   <li>GenericObjectNodeEditor</li>
 *   <li>CheckBoxNode</li>
 *   <li>CheckBoxNodeEditor</li>
 *   <li>NumberNode</li>
 *   <li>NumberNodeEditor</li>
 *   <li>DefaultNode</li>
 * </ul>
 * 
 * These classes are responsible for 
 * representing the different kinds of tree nodes that will be 
 * contained in the JTree object, as well as the renderers and editors
 * that will be responsible for displaying their properties in the
 * user interface.  
 * <p/>
 * Code for this class was inspired and partly borrowed from the 
 * following excellent tutorial on creating custom JTree renderers 
 * and editors authored by John Zukowski: <br/>
