First implementation of style in IEEEtran style

The paper is no longer using LuaLaTeX, but raw LaTeX (that saves a DVI), it
is so much faster! Initially I had used LuaLaTeX to use special fonts to
resemble the CODATA Data Science Journal, but all that overhead is no
longer necessary. Therefore I also removed the MANY extra LaTeX packages we
were importing. The paper builds and is able to construct one of its images
(the git-branching figure) with only 7 packages beyond the minimal
TeX/LaTeX installation. Also in terms of processing it is so much faster.

The text is just temporary now, and mainly just a place holder. With the
next commit, I'll fill it with proper text.
