      Thomas Medioni authored
      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
