After d669afb2 there was still
a fix in EffectiveEnergyDrift.cpp when a domain had zero atoms.

This could affect real calculations, so I think this fix should be
backported to v2.3

Fixes #246

(cherry picked from commit 97d7c422)

There was a bug in driver with --debug-pd when, unluckily, the
last domain had by chance zero atoms

Notice that before this fix the first sentence of the page was shown in
the summary ("Related Pages" page). Now it is not shown anymore, which is better.

To add a sentence for the summary (sort of subtitle), add a \brief command
(as in mdTemplate.md)

I renamed all files from .txt to .md so that they can be
visualized on github.

In addition, I renamed all files to have a name consistent with the content.
This makes manual portions easier to find.

Notice that I left the original labels (e.g. "Syntax" instead of "Getting Started")
not to break direct links to manual, though I think we should rationalize these names
as well.
