  Theory of Kingman's partition structures has two culminating points: the
general paintbox representation, relating finite partitions to hypothetical
infinite populations via a natural sampling procedure, known as Kingman's
paintbox; a central example of the theory - the Ewens-Pitman two-parameter
family of partitions.
  In these notes we further develop the theory by passing to structures
enriched by the order on the collection of categories; extending the class of
tractable models by exploring the idea of regeneration; analysing regenerative
properties of the Ewens-Pitman partitions; studying asymptotic features of the
regenerative compositions.
