Detailed Description

Analytic cross-asset lgm equity option engine.

This class prices an equity option analytically using the dynamics of a CrossAssetModel. The formula is black-like, with the variance of the underlying equity being dependent upon the dynamics of related interest and FX rates within the CrossAssetModel universe. See the book "Modern Derivatives Pricing and Credit Exposure Analysis" by Lichters, Stamm and Gallagher.
