The GBM has no constant coefficients, since it's coefficients are
dependant on S also.

That's why I want to use a GBM; it represents a different SDE.

I can adapt the MCHimalayaEngine to get the riskFreeRate from somewhere
else, but my original question was, whether there is anywhere deep in
the MC code that also demands the StochasticProcess derived class to
actually be a (Generalized)BlackScholesProcess...
