Used iconv -f iso-8859-1 -t utf-8 to convert some ISO-8859 files into UTF-8.
Reason: Debian's linter complains about non-utf8 encoding in installed
documentation files.
Note: file 'examples/bts/95_char_encoding_latin1.mlw' still contains iso-8859
encoding, but it is on purpose for testing. Debian does not complain about
that file, anyway.
- all programs with sessions are in examples/
- all programs without sessions are in examples/in_progress/
(if you have private sessions for those, just move them there)
- all pure logical problems are in logic/
(to simplify bench scripts and gallery building; they are few anyway)
- all OCaml programs are in examples/use_api/
- all strange stuff is in examples/misc/
(most of it should probably go)
- Claude's solutions for Foveoos 2011 are in examples/foveoos11-cm/
(why do we need two sets of solutions for quite simple problems?)
- hoare_logic, bitvectors, vacid_0_binary_heaps are in examples/
Bench scripts and documentation are updated.
Also, bench/bench is simplified a little bit.
