[Boost-users] ternary search trie

Hi, Does the BOOST library (somewhere) contain a ternary search trie container type (as described by Robert Sedgewick in his "Algorithms - 3ed edition" or here: http://www.cs.princeton.edu/~rs/strings/) that can by used as a standalone container (such as for example STL's map) ? I don't find something like this listed on the Boost library page (http://www.boost.org/libs/libraries.htm). Any help will be greatly appreciated, Thanks Sybrand
