The issue is that I don't want to disable the warning completely: I think it should still be there when you actually use the sample data set, just not every time you import mne. So editing version.txt wouldn't work. What I tried to do is to only check the version when you actually use `data_path`, as opposed to just `has_dataset` (from `dataset/utils.py`), but this probably isn't a great idea. Perhaps what we actually want to do is remove `from . import datasets` from the global `__init__.py`, same as I did for `tests`?
