/**
* Provides interface specification and implementation of volatility surfaces, e.g.,
* interest rate volatility surfaces like (implied) caplet volatilities and swaption
* volatilities.
* Volatility surfaces are mappings (t,K) → f(t,K), usually given by a discrete
* set of points and an interpolation and extrapolation method or a functional form
* (like the SABR model).
