Python class that builds a vocabulary and computes tf-idf scores

Need to Tokenize a piece of text and add the entries to the class's counts.

Fixes the vocabulary as static, prevents keeping additional vocab from

being added

Return the frequence of a word if it's in the vocabulary, zero otherwise.

Compute the inverse document frequency of a word. Return 0.0 if

the word has never been seen.
