Bad DOS value normalization

We assume that VASP, Exciting, and FHI-aims are all producing dos values a like. Which does not seem to be true. In the encyclopedia this discussion exists: encyclopedia-gui#111 , it highlights all the differences. Therefore, also the normalized value is wrong, because the normalizer is applying the same treatment for all codes. Does the encyclopdia pre-processing/normalizer do something different?

@mkuban, @himanel1, @temokmx, maybe you have more input on that.

@mkuban, if you find some examples that highlight this, please add it to the discussion here!
