J. Křentínský, and S. Sickert, submitted to LICS'18. We should add
proper references to the code and documentation once that paper is
accepted.

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.

spot::acc_cond::rabin_like_pairs().
