6 \brief A class holding Deep Inelastic Scattering (DIS) Form Factors
7  (invariant structure funstions)
8 
9  This class is using the \b Strategy Pattern. \n
10  It can accept requests to calculate itself, for a given interaction,
11  that it then delegates to the algorithmic object, implementing the
12  DISStructureFuncModelI interface, that it finds attached to itself.
