Simplify top-level table of contents and create the user guide which
includes the application development primer and other guides and
refereces instead of having them at the top-level.
Also move glossary section away from top-level TOC and remove broken
search link.

Promote a glossary.rst up into the doc/ folder, merge wiki
glossary entries (and remove from the wiki), and format use
the .. glossary directive to allow references by using the
:term: role (using :term:`ISR` will make a link to the
glossary entry for ISR)
