Faceting formatting and indexing improved for book

The bulk of the formatting for the Faceting chapter of the book for EAR#2 is now complete. This includes all of the section headers and indexing of terms, as well as a clean table for the faceting parameters. That means that the bulk of the work that I intended to complete for EAR#2 is now finished. There are still a lot of smaller issues that I wanted to get to, and will, but overall EAR#2 is now close at hand and on schedule for release by the end of the coming week.
