node_classes.py has too many lines

[AWhetter]

I am about to merge #458 but it is failing the pylint check because the docstrings have made the module too big. I didn't want to start moving things around so for now I have disabled the message, until we figure out how we want things laid out.

We could definitely start splitting it up, but I don't mind having the error disabled for now.

What do you think about making nodes a subpackage, moving nodes.py into nodes/__init__.py
Move node_classes and scope_nodes into this subpackage. For important nodes like NodeNG we could create single files per class e.g. nodes/nodeng.py , and move some of the assist functions into a nodes/util.py.
This would help with organization, split up large files, and prepare for #329

[PCManticore]

I wouldn't mind some of these refactorings, @brycepg although I'm not sure we'll ever do #329

[PCManticore]

I think this is fine as it is right now, as per my reasoning from #587. If the file would grow larger than it is right now, I'd say we should split it, but not the nodes themselves, rather any functionality that doesn't necessarily belong there.

Reopening because of the argument here : #587 (comment)
