>
> Word2VecModel is missing a method that allows for performing analogy-like
> queries on word vectors (e.g. King + Woman - Man = Queen). This is a
> functionality common to other word2vec implementations (see gensim) and is a
> major component of word2vec's appeal as cited in seminal works on the model
> (https://code.google.com/archive/p/word2vec/).
> An implementation of this method, findAnalogies, should accept three
> arguments:
> * positive - Array[String] of similar words
> * negative - Array[String] of dissimilar words
> * num - Int number of synonyms or nearest neighbors to calculated vector
