/**
* call-seq:
* URIClassifier.new -> URIClassifier
*
* Initializes a new URIClassifier object that you can use to associate URI sequences
* with objects. You can actually use it with any string sequence and any objects,
* but it's mostly used with URIs.
*
* It uses TST from http://www.octavian.org/cs/software.html to build an ternary search
* trie to hold all of the URIs. It uses this to do an initial search for the a URI
* prefix, and then to break the URI into SCRIPT_NAME and PATH_INFO portions. It actually
* will do two searches most of the time in order to find the right handler for the
* registered prefix portion.
