Minor issue in "lib/utils.py".

[u42dani]

I noticed line 139 in "lib/utils.py" should be modified
from model = gensim.models.Word2Vec(Sentences(self.documents), size)
to model = gensim.models.Word2Vec(sentences=Sentences(self.documents), size=size)
I guess the parameter list of the Word2Vec constructor changed...

Thanks! Does that work with gensim==2.1.0 (the version used during the development of this code)?
