New macro: \NL for naive cotangent complex
The naive cotangent complex is an important ingredient to several
topics discussed in the Stacks project. It deserves its own macro.

Some material about obstruction theories
This includes the notion of a naive obstruction theory and a
proof that such a thing is good enough to give openness of
versality. This was introduced on the blog
http://math.columbia.edu/~dejong/wordpress/?p=2472
It is just working out what you would get if you actually had an
algebraic stack. It seems likely that Artin was motivated in
formulating his axioms by the idea that such a thing should
exist.
Hopefully we can use this to prove openness of versality for
some nice cases such as families of proper flat algebraic
spaces... We'll see.
