Class Overview

Utility for case folding Java Strings. This follows the advice given here. Basically the value is case folded by calling String.toUpperCase(locale).toLowerCase(locale). This is a little better than calling only String.toLowerCase(locale). For example, in German the string "ß" upercase equilavent is "SS". If we only called only toLowerCase(java.util.Locale) we would store "ß"in the index which would make matching "SS" impossible. This does not always case fold correctly, for example the Turkish 'I', but it is a good compromise.
