Detailed Description

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 is a copy of the QL CapFloorTermVolSurface but gives the option to use BiLinear instead of BiCubic Spline interpolation. Default is BiCubic Spline for backwards compatibility with QuantLib
