In issue #16, we want to replace "Janus Graph" with "JanusGraph", which shortens the headings by a single character. However, the AsciiDoc headings currently in use have the same # of characters are the headings, e.g.,

Heading
~~~~~~~

That said, this is a deprecated heading, and was fixed in JanusGraph in this commit which also says:

As described in the Asciidoc best practices document:
http://asciidoctor.org/docs/asciidoc-recommended-practices/#section-titles
using heading markers using underlines of various characters is not recommended
for several reasons:

• hard to remember which character means which level header
• hard to maintain the correct number of characters (must match heading line)

That commit also includes a complete Python script for making this update for AsciiDoc files, which will be used to convert the headings to the new recommended format, and make it easier to cleanup the name format.
