Detailed Description

A class holding Deep Inelastic Scattering (DIS) Form Factors (invariant structure funstions)

This class is using the Strategy Pattern.
It can accept requests to calculate itself, for a given interaction, that it then delegates to the algorithmic object, implementing the DISStructureFuncModelI interface, that it finds attached to itself.
