Detailed Description

Helper class to extend an OptionletStripper1 object stripping additional optionlet (i.e. caplet/floorlet) volatilities (a.k.a. forward-forward volatilities) from the (cap/floor) At-The-Money term volatilities of a CapFloorTermVolCurve.

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

Implements LazyObject.
