Major changes, when compared to the original Basho-internal document:
* Start removing strong consistency topics to a separate doc (unfinished)
* Remove section on per-file metadata management: it was too speculative IMHO
* Remove the following sections (numbering is relative to v3 of internal doc):
7.2.1 scenario 1, 13.3, 14
* Move the "Recommended Reading" section to the end
