Provides a set of classes for setting properties by custom editors.
If there exist special custom editor for property, there appears small
"..." button which invokes such custom editor dialog. Custom editor is embedded
in a dialog. If it is property of a component from Form Editor, dialog contains
Default, OK and Cancel buttons, combo box enabling to change editor (e.g.
PointEditor/Form Connection), button "Advanced" to call "Advanced Initialization
Code" dialog (see {@link org.netbeans.jellytools.modules.form.properties.editors}).
Otherwise it is dialog with OK and Cancel buttons (Default and Help are optional).
A custom editor is extended from NbDialogOperator. Custom editor operator contains high-level
methods to get or set compound property value in one method by custom editor.
These methods are then used in tests or in specialized property implementation
(see {@link org.netbeans.jellytools.properties}).
