  Container of TPersist instances that are  unique per concrete type .

  This class acts as a container of TPersist instances where only a single

  instance of a given most-derived type can be stored.

  This is typically useful to \a overwrite objects of a given type, typically

  configuration options, without discarding the other objects.
