Notes:
******

    - in the context of calculations wihtout spin-orbit coupling the time reversal
      symmetry only determines whether a full BZ or just a half of it should be used

    - in case of Bloch spectral function calculations a specific k-mesh is defined by
      parameters in the `[BSF]` section and `[Kpoints]` parameters are ignored
