==================
- Copy ``IObjectMovedEvent``, ``IObjectAddedEvent``,
``IObjectRemovedEvent`` interfaces and ``ObjectMovedEvent``,
``ObjectAddedEvent`` and ``ObjectRemovedEvent`` classes here
from ``zope.container`` (plus tests). The intent is to allow packages
that rely on these interfaces or the event classes to rely on
``zope.lifecycleevent`` (which has few dependencies) instead of
``zope.container`` (which has many).
