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.
