We can now either compile & link the library, or
include header-only (almost, but the structure is there).

Technically, we broke the old C RAW API.
but it was just created, and we are in prealpha.
And we only put things const. so whatever.

Spaces, not tabs.

Actually, I liked tabs much more. But it seems a lot
of IDEs and general reader do not handle them correctly,
or do not let you configure "1 tab == 4 spaces", so the code
was not always readable.

"git diff -w" for this commit is en empty list.
