reduceToRelations bekommt den aktuellen Graph, einen Klassenknoten darin sowie eine Liste mit Relationsnamen,

die _nicht_ angezeigt werden sollen, �bergeben. Ausgehend von dem Klassenknoten werden aus dem Ontologiegraphen

transitiv alle Klassenknoten ermittelt, die �ber eine der nicht-ausgeblendeten Relationen erreicht werden

k�nnen. Diese werden (mit ihren Relationen zu ebenfalls neu hinzugef�gten Knoten) in den aktuellen Graphen

eingef�gt. Bez�ge zwischen neu eingef�gten Knoten uns alten????

Im ersten Schritt werden transitiv alle Knoten ermittelt, die mit dem ausgew�hlten Knoten in einer der

nicht verbotenen Beziehungen stehen. Dann wird rekursiv f�r jeden dieser gefunden Knoten dessen direkte

Subklassen ermittelt und f�r diese wiederum die direkten Nachbarn ermittelt und aufgenommen.
