Detailed Description
Hybrid Heston Hull-White stochastic process.This class implements a three factor Heston Hull-White model
Bug
- This class was not tested enough to guarantee its functionality… work in progress

void update () [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.Reimplemented from StochasticProcess.
