Tetsuo Kiso 38e145e556 Use util::TokenIter to tokenize n-best lists.
Reduce creating std::string objects, too. In both ScoreArray
and FeatureArray classes, the private members to track sentence
indices (namely, "m_index") were unnecessarily declared as
std::string, but it's better to directly declare them as 'int'.
