Show hierarchy information

[nichtich]

Given a decomposition and information about member classes we can show which parts of the decomposition follow the class hierarchy, e.g.

   7----- Künste und Unterhaltung
↳ 70---- Künste
↳ 700--- Künste
↳ 700.2- Standardschlüssel für die Künste
↳ 700.2- Verschiedenes
   -0---- Facettenindikator
   --0--- Hilfstafel 1. Standardschlüssel
↳ --0.2- Verschiedenes
↳ --0.23 Das Thema als Beruf, Erwerbstätigkeit, Freizeitbeschäftigung

We could also highlight the last concept in a hierarchy as bold because it is the most specific and therefore probably the most relevant one, right?
