Terminology requests

[Lucretiel]

For the assistance of implementers, I'd like to propose we add a set of terminology to help group related concepts in KDL. Specifically, I'm interested in a unifying term for:

• The properties and arguments associated with a node.
• The properties, arguments, and the set of children associated with a node.

In kaydle I've been using "Entity" interchangeably for both of these, but I don't love that. I was thinking something like a "Component" (for all things belonging to a node) and "Primitive Component" (for everything except the set of children). Of course, I'm happy to hear bikeshedding for this. Under this model, a single component would be any individual value, an individual property (the key-value pair collectively), or the set of children as a whole.

This terminology shouldn't really be needed by actual KDL users, but it'll be convenient for implementors to be able to have a common term to refer to all of the things belonging to a single node, because often these are iterated / grouped collectively in the course of parsing.

entity sounds fine by me. Everything else I can think of has a lot of overlap with other languages that would prove confusing?

I also can't think of anything better than entity.

I'm using entity now for the props/values object, and yeah, it works fine for me.
