This currently only allows extra check for stutter invariance.
* src/bin/common_aoutput.cc: Add check option,
and test stutter invariance.
* src/twaalgos/stutter.cc, src/twaalgos/stutter.hh
(check_stutter_invariance): New function.
* src/tests/stutter-tgba.test: Test it.
This addresses the easy part of #79.
* src/twaalgos/postproc.cc: If the input is already BA and we want a BA
as output, do not try the transition-based simulation only to
degeneralize the result.
* src/tests/optba.test: New file.
* src/tests/Makefile.am: Add it.
* src/twaalgos/dotty.cc: Add an option (e) to force elliptic shape, and
a heuristic to choose between circle and ellipse by default.
* src/bin/common_aoutput.cc, src/bin/dstar2tgba.cc: Document 'e'.
* src/taalgos/dotty.cc: Ignore 'e'.
* wrap/python/spot.py (setup): Do not force circular states. The
default should be fine.
* src/tests/det.test, src/tests/dstar.test, src/tests/monitor.test,
src/tests/neverclaimread.test, src/tests/readsave.test,
src/tests/sccdot.test, src/tests/tgbagraph.test: Adjust expected
results.
* NEWS: Adjust.
* src/twaalgos/dotty.cc: Add option 'B'.
* src/taalgos/dotty.cc: Ignore it.
* src/bin/common_aoutput.cc, src/bin/dstar2tgba.cc: Document it.
* wrap/python/spot.py (setup): Use it by default, and rewrite
the function to be a bit more flexible.
* wrap/python/tests/automata-io.ipynb, wrap/python/tests/automata.ipynb,
wrap/python/tests/piperead.ipynb, wrap/python/tests/randaut.ipynb,
wrap/python/tests/testingaut.ipynb: Use setup() everywhere.
