For #262.

This would be nice to have before official code review, but not essential. Certainly we should have it done before @veillette's sabbatical ends.

I'll assign this one to myself.

Assigning to @pixelzoom as well.

The section titled Query Parameters duplicated the information in CalculusGrapherQueryParameters.ts, and would be likely to get out of sync. Since dev and QA are used to reading query-parameter schemas, I replaced that section with a link to CalculusGrapherQueryParameters.ts.

I added a Termninology section that needs to be fleshed out. I think we can keep this very brief. No need to include general math terminology, only sim-specific terms that might not be obvious, and would help someone reading the code.

I added a section about PHET-IO with a short stub. Assigning to @pixelzoom who be able to add something more cogent/relevant.

implementation-notes.md is not delivered with a release. So we can continue to make changes after the release branch is published, and there's no need to cherry-pick to the release branch.

I went over the implementations-notes. It is a good description and if we compare it to other sim's implementations-notes, we are raising the bar. Closing.
