Done with my merge in r2899. Built-in PDFs can be selected via the key pdf_builtin, the set can be switched via $pdf_builtin_set, and the path to the grids can be changed with $pdf_builtin_path. On the technical side, I have added a new structure function (module) sf_builtin_pdf and a directory src/pdf_builtin which contains the slightly modified PDF codes and a wrapper. The shipped grids are installed in $prefix/share/whizard/pdf_builtin.
I have opened #386 for discussing the list of included PDF sets.
On the testing side, I have compared u u -> u u , d d -> d d etc and g g -> g g for all partons between CTEQ6L and LHApdf/CTEQ6L, and the result agree nicely. Because of #384, I have not yet checked MRST2004QED (still working on it), but the results look reasonable.
This will be handled by CS earlier than the BLHA ticket.
