> The ICUTokenizer produces unigrams for CJK. We would like to use the ICUTokenizer but
have overlapping bigrams created for CJK as in the CJK Analyzer.  This filter would take the
output of the ICUtokenizer, read the ScriptAttribute and for selected scripts (Han, Kana),
would produce overlapping bigrams.
