eisa.txt: standardize document format

Each text file under Documentation follows a different
format. Some doesn't even have titles!

Change its representation to follow the adopted standard,
using ReST markups for it to be parseable by Sphinx:

- use ReST notation for titles;
- identify literal blocks;
- use :Author: for document authorship;
- use the proper notation for tables;
- adjust whitespaces where needed.
