PhraseTokenizer

class PhraseTokenizer extends DocumentAnnotator

A tokenizer which will merge existing tokens if they are from one of the phrases given.

Efficiently uses a trie-like data structure to simulate the finite automaton for tokenization. The behavior is that if there is a long and a short phrase with the same prefix the longer one will be picked greedily.

This version gets all attributes from the last token in the phrase.
