I neither have nor use ditaa. I was going to test out an asciidoctor plugin*
but failed in that I can not get the thing to install on Windows. It should have
taken the ASCII graphic chart and spit out a nice SVG file that was then
linked in automagically.

Fine with me if it looks better / is more maintainable than the mess I made.
Probably best to remove the pseudo-ditaa header though.
