Polarized evolution

[felixhekhorn]

reproduce hep-ph/0511119

• tables are collected in the results folder
• status:
  • eko: complete
  • apfelxx: complete
  • Pegasus: complete
  • Hoppet: central only
  • QCDNUM: central only

confirm $L_-$

bug confirmed ✔️ - I suggest to put the corrected numbers into the paper

perform benchmark at NNLO

I suggest:

• NNLO FFNS evolution: table 19 and the scale variation part 1+2+3 as before
• NNLO VFNS evolution + NLO transition matrix elements: table 20 and the scale variation part 1+2+3 as before
