implement dualize to complement automatons
* NEWS: Mention the implementation * python/spot/impl.i: Add dualize() to python interface. * spot/twaalgos/Makefile.am: Add dualize.cc,hh to the build * spot/twaalgos/dualize.cc: Implement dualize() that takes an automaton and returns its dual * spot/twaalgos/dualize.hh: Implement dualize() * tests/Makefile.am: Add dualize tests to the test suite * tests/python/dualize.py: Test cases for dualize
