Useful __all__ and no * import

[flying-sheep]

Your example notebooks import stuff from utils and import core as scLVM

that’s unnecessary if you import only the useful stuff in __init__.py.

then users can simply do

from scLVM import load_data, scLVM, ...
# or
import scLVM
d = scLVM.load_data(...)
