> While I understand some of the reasons for its design, the original LowerCaseTokenizer should have been named LowerCaseLetterTokenizer.
> I feel that LowerCaseTokenizer makes too many assumptions about what too tokenize, and I have therefore patched it.  The *default* behavior will remain as it always has--to avoid breaking any implementations for which it's being used.
> I have changed LowerCaseTokenizer to extend CharTokenizer (rather than LetterTokenizer).  LetterTokenizer's functionality was merged into the default behavior of LowerCaseTokenizer.
> Getter/Setter methods have been added to the LowerCaseTokenizer Class, allowing you to turn on / off tokenizing by white space, numbers, and special (Non-Alpha/Numeric) characters.
