Adds the method spot::acc_cond::is_streett_like() that behaves like spot::acc_cond::is_streett() except that it works on a wider range of acceptance conditions, called Streett-like. Also adds spot::acc_cond::streett_like_pairs() that returns a boolean assessing whether the acceptance condition is Streett-like and also returns all the Streett_like pairs. Defines the new struct type spot::acc_cond::rs_pair. Similarily, Adds the methods spot::acc_cond::is_rabin_like() and spot::acc_cond::rabin_like_pairs(). * NEWS: Mention this modification * python/spot/impl.i: Declares the new struct to SWIG, and defines the streett_like_pairs() vector as an output parameter, which makes the python code return a tuple (boolean, vector) rather than a pass-by-reference vector. * spot/twa/acc.cc, spot/twa/acc.hh: Declares an implements the new methods and the new nested struct. * tests/Makefile.am: Add new tests to the suite * tests/python/rs_like.py: Tests the new methods and the SWIG bindings.
