This patchset adds documentation on document encryption. It also adds appropriate references to other sections of the documentation where linking to document encryption is apropos. Finally, this patchset adds further information and structure around the document rendering process in general, in order to underscore the pieces of documentation that undergird the general concept of document rendering: substitution, layering and replacement.

Document Rendering
Document rendering involves extracting all raw revision documents from Deckhand's database, retrieving encrypted information from Barbican, and applying substitution, layering and replacement algorithms on the data.
The following algorithms are involved during the rendering process:
substitution
Substitution provides an "open" data sharing model in which any source document can be used to substitute data into any destination document.
layering
Layering provides a "restricted" data inheritance model intended to help reduce duplication in configuration.
replacement
Replacement builds on top of layering to provide yet another mechanism for reducing data duplication.
