Detailed Description

In order to compute market vegas, we need a class that gives the derivative of a cap implied vol against changes in pseudo-root elements. This is that class.

The operation is non-trivial because the cap implied vol has a complicated relationship with the caplet implied vols.

This is tested in the pathwise vegas routine in MarketModels.cpp
