cJSON aims to be the dumbest possible parser that you can get your job done
with. It's a single file of C, and a single header file.

JSON is described best here: https://www.json.org/ It's like XML, but fat-free.
You use it to move data around, store things, or just generally represent
your program's state.

As a library, cJSON exists to take away as much legwork as it can, but not
get in your way. As a point of pragmatism (i.e. ignoring the truth), I'm
going to say that you can use it in one of two modes: Auto and Manual.
Let's have a quick run-through.

I lifted some JSON from this page: https://www.json.org/fatfree.html
That page inspired me to write cJSON, which is a parser that tries to share
the same philosophy as JSON itself. Simple, dumb, out of the way.
