Detailed Description
Local volatility surface derived from a Black vol surface.For details about this implementation refer to "Stochastic Volatility and Local Volatility," in "Case Studies and Financial Modelling Course Notes," by Jim Gatheral, Fall Term, 2003

- Bug:
- this class is untested, probably unreliable.
