Detailed Description

cp_wtrie is a wide character trie implementation. Tries allow for prefix matching with O(m) = O(1) time (m being the length of the key). Used to store key - value mappings, tries have certain advantages over hashtables in that worse case behavior is still O(1) and no hash function is needed. cp_wtrie is technically a compact trie in that collapses unused character paths.
