[Pw_forum] coordination system for polarizations in matdyn.modes

[lfhuang]

Dear prof. Isaev:
    Thank you for your help and correction! Yes I had mixed "polarization" and "epsilon" due to not taking the 
designation "polarization" seriously before. 
    Thank you very much!
Best Wishes!

Yours Sincerely
L.F.Huang
