Class VariableGapTermsIndexWriter

Selects index terms according to provided pluggable VariableGapTermsIndexWriter.IndexTermSelector, and stores them in a prefix trie that's loaded entirely in RAM stored as an FST<T>. This terms index only supports unsigned byte term sort order (unicode codepoint order when the bytes are UTF8).
