+	This is an implementation of double-array structure for representing trie, 
+	as proposed by Junichi Aoe.
+	Trie is a kind of digital search tree, an efficient indexing method in which
+	search time is independent of database size. It only takes O(m) search time,
+	where m is the length of the search string. Comparably as efficient as hashing,
+	trie also provides flexibility on incremental matching and key spelling
+	manipulation. This makes it ideal for lexical analyzers, as well as spelling
+	dictionaries.
