Issue title: Name Bikeshedding
 Issue body: I would like to come up with a specific branded name for ***TNG-wrapped function***, because that phrase is too cumbersome and not well-descriptive of its nature. The analog of it, in React, is a "component", or more specifically "stateful function component".

I don't imagine that making TNG-wrapped functions will be limited to rendering components. But that's certainly one of the many possible use cases. So I don't necessarily want to limit them with "component" or "component function" or whatever.

Some names to consider:

* "TNG function" -- don't really like that, since `TNG(..)` is a specific utility, **a function**, that wraps the functions in question
* "stateful function" -- this is decent, and describes its main characteristic well, but it's also kinda blah

Other thoughts?

 Comment 0: You could pretend that “TNG” is a verb and use the term **TNGed function**.

This opens up some nice variants like:

- “I recommend **TNGing** that function”
- “Are you sure that you that function is **TNGable**?”
 Comment 1: Some name ideas that I'm considering:

* "Articulate", "Articulate Function" -- bonus: it's also the verb, as in "Articulate the function", and the descriptor of it, "Articulated Function"

* "Subject", "Subject Function"

* "Relation", "Relation Function", "Relational Function"

* "Captive Function"

* "Substrate Function"
 Comment 2: I propose to select "Articulate Function" to describe a function that has been TNG-wrapped to provide the hooks context (state, effects).

Please vote thumbs up or thumbs down on this selection. Thanks! :)
 Comment 3: Seriously though, what about Articulated Functions?

articulated (adjective)

having two or more sections connected by a flexible joint.
 Comment 4: OK, I'm satisfied, we'll pick "Articulated Function" (to replace "TNG-wrapped function") for describing normal functions which are *decorated* with a TNG hook context. Docs updates to follow.
