/**
 * A <code>BeanContextMembershipEvent</code> encapsulates
 * the list of children added to, or removed from,
 * the membership of a particular <code>BeanContext</code>.
 * An instance of this event is fired whenever a successful

 * invoked on a given <code>BeanContext</code> instance.
 * Objects interested in receiving events of this type must
 * implement the <code>BeanContextMembershipListener</code>
 * interface, and must register their intent via the
 * <code>BeanContext</code>'s
 * <code>addBeanContextMembershipListener(BeanContextMembershipListener bcml)
 * </code> method.
