-/**
- * Intraprozedurale Analyse zur Abschätzung der Aufrufrelation. Es wird
- * die Menge der instantiierten Klassen bestimmt, und daraus eine Abschätzung
- * der aufgerufenen Methoden.
- *
- * Voraussetzung ist, dass das Programm keine Methodenzeiger handhaben kann.
- * In diesem Fall koennten Methoden verloren gehen. Oder wir muessen nach
- * allen "freien" Methoden suchen (siehe cgana).
- *
- * @@@ Die Analyse sollte wissen, von welchen Klassen Instanzen ausserhalb
- * der Uebersetzungseinheit alloziert werden koennen. Diese muessen in
- * die initiale Menge allozierter Klassen aufgenommern werden.
