One minimal usage example

[emersonthis]

This library appears to be exactly what I need, but I'm having trouble figuring out how to use it and which are the minimal dependancies required to build a trie and then run lookups on it. When I try to load /scripts/ptrie-complete.js I get:

ReferenceError: namespace is not defined
    at Object.<anonymous> (/Users/ESL/Desktop/hola/trie-test.js:1:442)
    at Module._compile (module.js:434:26)
    at Object.Module._extensions..js (module.js:452:10)
    at Module.load (module.js:355:32)
    at Function.Module._load (module.js:310:12)
    at Function.Module.runMain (module.js:475:10)
    at startup (node.js:117:18)
    at node.js:951:3

Weirdly, I get this same error even if I include /scripts/namespace.js before it. It's not obvious to me what namespace.js is...

I would love just a couple lines of code demonstrating how these fils are intended to be used. The index.html file is almost this, but it's currently broken at the moment because it tries to load resources that do not exist anymore.
