Using nomad-lab

Currently it is very hard to sensibly use nomad-lab without the plugins. For the new gui, i am using a simple pyenv with just "pip install nomad-lab", but this will apply to other nomad-lab users as well.

• currently (develop) the C parsers are in the package, but the schemas have been (partially) removed. Without excluding all C parsers/normalizers in the nomad.yaml, I can do almost nothing with nomad-lab, because parsers gets imported all the time and this import fails because the C parsers cannot import their schema. I am forced to also install the C plugins or exclude them explicitly.
• even with explicitly excluding all C parsers, example_uploads.yml is missing from the nomad-lab package and I get an error on loading the app.

added bug bugfixes current labels

@himanel1, I think the missing example_uploads.yml is something you can fix rather quickly?

@ladinesa, I guess we are in the middle of things. The problems probably goes away once we also removed the C parsers (and normalizers) from nomad-lab. If this happens, lets say in the next 2 weeks, its fine. Otherwise, we have to come up with some intermediate fix. In this condition, I cannot release a new version of nomad-lab. We can discuss Wed and Fri.

This could be a road to resolve this:

• dependencies/normalizers/*: remove
• dependencies/parsers/*: remove
• nomad.datamodel.metainfo.simulation: remove
• atomutils.py: refactor/clean remove MD related functions from atomutils localize pymatgen imports in Formula class localize scikit imports
