207992a71d introduce store and store objects without file system details
this leaves open implementation details, especially about store paths
and file system objects, and allows explaining them together were it is
more appropriate. also leaves room to carefully introduce the key
insight behind Nix: applying results from programming language theory to
the operating system paradigm of files and processes.

e72a7874dc beautify rosetta table
while this may eventually introduce ugly diffs, the table will now
render readably on the terminal (e.g. for `man nix` or `nix --help`)
without further intervention.

d5eea66615 introduce build tasks
while it appears a bit much for the overview, this way we set the stage
for going directly into data types when describing the store, instead of
first having to say what build tasks are and how they relate to build
plans.

7c3bca1372 revert to build plans in top-level overview
do not introduce build tasks yet, that is the next level of detail.

2303f84a68 revert to "build plan" in overview diagram
this displays correct composition again. build inputs and build results
are not part of build plans in terms of data objects.

also this is a much less complicated setup. this will be the first
impression of architecture, and we want to get it right.

0e63b9bf88 add link from overview to store section
the overview should only link to the three main concepts presented. the
store is now fairly fleshed out. others can follow later.

902638c519 build step -> build rule
"step" sounds atomic, while "rule" hints at internal structure, which in
our case consists of mapping inputs to outputs using build instructions.

5fda995491 formalize file system objects
convention: describe every data type in prose, and illustrate with
a class diagram, and a textual representation of an abstract
data type.

right now we save ourselves the trouble of doing class diagrams, we can
add them later. but they are important.

fb2ec7e4ec reword section on references
use file Contents instead of Data, as that flows more naturally in the
prose.

simplify explanation of the idea behind scanning for store paths

remove references to unfinished sections.

attempt to explain used and documented terminology, as well as how
