a5be5e0120 doc/manual: define {local,remote} store, binary cache, substituter
Nix veterans intuitively know what the following terms mean.  They are
used in several places in the nix documentation, but never defined:

- local store
- remote store
- binary cache
- substituter

In particular, I found the last two terms to be confusingly similar.
Let's give definitions for them.

a28d6878b2 concept map: put closure as it is in the chapter

key idea on which most of Nix operates.

631ca18ee6 reword notes on copying
clarify that we are copying between different stores. we have not
introduced that notion or why it would be interesting, but for now it
should be fine to keep it in context of the store directory.

we could move that later to a more detailed explanation of different
store types.

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.

d5eea66615 introduce build tasks
while it appears a bit much for the overview, this way we set the stage

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.
