Cap/floor smile volatility surface.
This class provides the volatility for a given cap/floor interpolating a volatility surface whose elements are the market term volatilities of a set of caps/floors with given length and given strike.

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 LazyObject.

This method must implement any calculations which must be (re)done in order to calculate the desired results.
