> Word2VecModel now stores the word vectors as a single, flat array; Word2Vec does as well. However, when Word2Vec creates the model, it builds an intermediate representation. We should skip that intermediate representation.
> However, it will be nice to create a public constructor for Word2VecModel which takes that intermediate representation (a Map from String words to their Vectors), since it's a user-friendly representation.
