> Sometimes you need to keep track of what was added and what was removed
> from a collection, and that is what we created TrackingCollection for.
> Additionally, since we were implementing lazy-loading of collections of
> persistent objects, we introduced a CollectionLoader that is used by the
> TrackingCollection when it has to access all of its elements. It is
> still possible however to use the TrackingCollection without a loader,
> and it will simply start empty and be considered loaded.
