bug#48580: Outline Mode using Phylogenetic Tree Nomenclature

[pietru]

The more familiar (emacs) names can be put in the description and mouse pop-up 
description.
But internally, a more formal system implemented.

I do not see that developers thought about tree structures in a formal manner
(e.g. leaves, branches).  Leaves are not bodies, and branches are not 
subheadings.

We are getting even more people thinking badly about tree structures, and having
other developers get used to faulty nomenclature.

What can be changed so that there could be some changes that can be handled, 
but not
too excessive?  There exists a really thought up system that outline should 
adopt.
It would need documentation for others to understand.

There can also be a deprecation process.

Regards
Peter
