PatternAnalyzer
Efficient Lucene analyzer/tokenizer that preferably operates on a String rather than a `Reader`, that can flexibly separate text into terms via a regular expression `Pattern` (with behaviour identical to `String.split(String)`), and that combines the functionality of `LetterTokenizer`, `LowerCaseTokenizer`, `WhitespaceTokenizer`, `StopFilter` into a single efficient multi-purpose class.

SynonymMap Loads the WordNet prolog file wn_s.pl into a thread-safe main-memory hash map that can be used for fast high-frequency lookups of synonyms for any given (lowercase) word string.
