Detailed Description

A deeply inelastic scattering event. Stores kinematics computed by different methods:

Using the scattered electron
Jacquet-Blondel method (uses hadrons)
Double-angle method (uses both hadrons and the scattered electron)

This is an abstract class, as it does not implement track methods inherited from VirtualEvent. The user must implement the appropriate methods for their track type in an inheriting class.
