Move developer docs into their own subtree

[Nolan Brubaker]

As of right now, all top level files in the 'doc' subdirectory are implied to be developer documentation. However, to make the docs more clear, we should probably move them into their own, dedicated section.

    Move developer documentation to its own subtree

    Prior to this change, all files at the root of the doc/source/ directory
    were implied to be developer documentation. This commit moves them into
    an explicit subdirectory, and re-words the section headings to be less
    repetitive.

    No changes to formatting or content were introduced.
