> Current dictionary vectorizer takes a set of text-files, creates the
> dictionary and convert them to text vectors. In a classification scenario,
> the vectorizer needs to take a Already existing dictionary and use the ids to
> convert text to vectors and optionally do the following
> 1. Choose between tf|tfidf weights (need to take the document frequency as an
> input for this)
> 2. Add new words to the dictionary and provide options to write it to the
> disk and read it back
> 3. Add option to normalize/lognormalize
