switch to pypi version of MolecularNodes

[BradyAJohnston]

I put Molecular Nodes up on pypi, so it can be installed from there and no longer requires
the internal packaging. The example .ipynb now works with the the installed version.

hi @BradyAJohnston , thanks for this pr!

Great to hear that molecular nodes is on pypi now!

This will make maintaining this package much more simple.

And actually, the previous implementation with that package folder was in the project did not working because of this line
https://github.com/BradyAJohnston/MolecularNodes/blob/dev-headless/MolecularNodes/auto_load.py#L57

I got this error, which is fixed now :)

ModuleNotFoundError: No module named 'MolecularNodes'

For the new version, I had to change import MolecularNodes as mn to import molecularnodes as mn and now it works like a charm!! :)

[BradyAJohnston]

yeah I don't know why it goes lowercase, any ideas?

[kolibril13]

I found

All comparisons of distribution names MUST be case insensitive, and MUST consider hyphens and underscores to be equivalent.

here: https://peps.python.org/pep-0426/#name

[BradyAJohnston]

It uses capital letters on PyPi (https://pypi.org/project/MolecularNodes/) but it just turns into lowercase when installed?

[kolibril13]

good question! ChatGPT saies:

When specifying dependencies in setup.py or pyproject.toml, the package names are case-insensitive, but the version specifiers are case-sensitive.

https://chat.openai.com/share/464b23d9-515b-4d77-8e27-c82d08c67cce

I don't know why it shows up with the capital letters on pypi.

[BradyAJohnston]

I found lots of discussion on the poetry repo (python-poetry/poetry#1538).

It seems to be somewhat unresolved. It is still unclear to me why on pypi it is listed with capitals, but installs as lowercase.
