Detailed Description

A class holding Quasi Elastic (QEL) Form Factors.

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