/**
 * This class represents one category (like "Ant"
 * or "Form Editor") in Miscellaneous Panel of Options Dialog.
 * Normally panels are registered using {@link OptionsPanelController.SubRegistration}.
 * They may also be registered in a layer manually as follows:
 *
 * 
 * <folder name="OptionsDialog">
 *     <folder name="Advanced">
 *         <file name="FooAdvancedPanel.instance">
 *             <attr name="instanceCreate" methodvalue="org.netbeans.spi.options.AdvancedOption.createSubCategory"/>
 *             <attr name="controller" newvalue="org.foo.ToDoOptionsController"/>
 *             <attr name="displayName" bundlevalue="org.foo.Bundle#LBL_Foo"/>
 *             <attr name="toolTip" bundlevalue="org.foo.Bundle#HINT_Foo"/>
 *             <attr name="keywords" bundlevalue="org.foo.Bundle#KW_Foo"/>
 *             <attr name="keywordsCategory" stringvalue="Advanced/FooSubTabInOptions"/>
 *         </file>
 *     </folder>
 * </folder>
 *
 * where:
 * 
controller should be an instance of OptionsPanelController
 * 
displayName should be a localized string for your tab display name
 * 
toolTip should be a localized string for your tab tool tip
 * Currently unused.
 * 
keywords should be localized keywords list, separated by comma in Bundle, for quickserach purposes
 * 
keywordsCategory should be relative path to your panel inside Options dialog
 * 


 * No explicit sorting recognized (may be sorted e.g. by display name).
