Broken package namespacing

[arpieb]

Tested the install via pip per #2 and worked fine. However, working through the tutorials and noticed:

1. The tutorial import statements have not been updated to reflect the pypi packaged namespace
2. Getting errors in alegnn/modules/architectures.py where incorrect module namespaces are used in evals

Nice catch! Did correcting the eval fix the issue?

I honestly got to a certain depth trying to, but there were so many I just stopped and opened the issue

I temporarily reverted all the changes since b32984, where this worked before. The new branch pip contains these commits now. I will update the tutorials as well.
