Detailed Description
Garman-Klass volatility model.
This class implements a concrete volatility model based on high low formulas using the method of Garman and Klass in their paper "On the Estimation of the Security Price from Historical Data" at http://www.fea.com/resources/pdf/a_estimation_of_security_price.pdf
Volatilities are assumed to be expressed on an annual basis.
