## Detailed Description

Finite-Differences Heston Hull-White Vanilla Option engine.

Tests:
  the correctness of the returned value is tested by reproducing results available in web/literature and comparison with Black/Heston pricing.

virtual

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.

Implements Observer.
