Where went `CSVDatasetZTNorm` ?
With recent csv-dataset
refactoring, some derived classes have been left on the side. With changes partially pushed to bob
a simple import like from bob.bio.face.database import MobioDatabase
will leads to:
ImportError: cannot import name 'CSVDatasetZTNorm' from 'bob.bio.base.database'
Which is quite inconvenient.
