nix-language: attempt to simplify concept overview ( #397 )
...
In the current text its not even for me clear what it is referring to. This rewrite tries to give more examples for each concept of the language.

fix wording on derivations
...
most importantly, derivations are not a special data type, but only
a certain kind of attribute set with two magic attributes.
we don't go into the details of the magic here, because it's really hard
to explain concisely. it would only distract from the surface feature
we care about here: composition through store paths.

rework parentheses example
...
it was reported that the list example was confusing and lacked
explanation.
moved the example to function application, and reduced the syntax notes
to "notes on whitespace". moved the emphasis on the goals of this
tutorial to its proper place in the introduction.
it's good to leave the whitespace notes in the introductory part,
because they are unspecific and clearly belong to the "don't worry, it
may look weird, but that doesn't matter" part.

it was reported that the NixOS configuration is confusing, because

added section headings to give hints where to look next.

This is the point in the tutorial where I started playing around with
paths and antiquotation in a `nix repl` session and got seriously
confused for a few minutes...

they are the least significant combination of frequency of occurrence
