/**
* 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/>
