The style package that I use. Note that it is intended that there are a lot of options that can be passed---a full documentation will come soon. Relatedly, this should be fully customizable--you can replace brwabase.sty and brwabox.sty with your preferred .sty's as desired.
Furthermore, please compile with LuaLaTeX or XeTeX, not pdfLaTeX. I personally use latexmk -pdflatex='lualatex' -pdf [tex document] from the Command Line.
Thanks to Jason Chen for extensive advice and to Daniel Zhu for general usefulness.
