Wanting a clean easy-to-use repository

[wendellpiez]

Describe the bug

Currently the toolchains especially the xslt-m4 folder is due for de-cluttering and defenestration of unused materials, as well as documentation.

Who is the bug affecting?

Present and future developers.

What is affected by this bug?

Clutter and confusion creates an unwanted degree of friction doing something that is already difficult.

Expected behavior (i.e. solution)

Everything in the repo should work; should be well documented; and should not be just "to save for later".

Other Comments

NB: retest everything as we go to ensure we drop nothing by moving too fast!

This Issue could be performed along with #163.

This is all to make good work better.

@david-waltermire-nist I propose we close this Issue, which might have been (but was not) linked to PR #172.
