/**
 * Extends BeanCustomizer. Exists primarily for those customizers
 * that can be displayed in the GenericObjectEditor (in preference
 * to individual property editors). Provides a method to tell
 * the customizer not to show any OK and CANCEL buttons if being 
 * displayed in the GOE (since the GOE provides those). Also specifies
 * the methods for handling closing under OK or CANCEL conditions.
 * 
 * Implementers of this interface should *not* use the GOE internally 
 * to implement the customizer because this will result in an cyclic 
 * loop of initializations that will end up in a stack overflow when
 * the customizer is displayed by the GOE at the top level.
