LuaLaTeX

Some LuaLaTeX code

Easy goals:

1. pass a TeX variable to Lua
2. print a Lua variable to PDF
3. pass a Lua variable to TeX

Main goals:

1. format a number in engineering notation with Lua and SIunitX
2. create a kind of \plot command, giving the filename of the data file
3. the same but for tables

Future goals:

1. create an adaptive LuaLaTeX document (for language, for objects, ...)
2. implement a sort of Errata Corrige revisioning system through Lua
3. build on top of adaptiveness in order to make secret environments during printing

Motivations
With the implementation of these high-level commands I'd like to make
writing a technical report easier.
