Detailed Description

A class to store PDFs.

      This class is using the \b Strategy Pattern. \n
      It can accept requests to calculate itself, for a given (x,q^2) pair,
      that it then delegates to the algorithmic object, implementing the
      PDFModelI interface, that it finds attached to itself.
