// JavaScript Document
// qs_score - Quicksilver Score
// 
// A port of the Quicksilver string ranking algorithm
// 
// Examples changed to fit jQuery model (JSK):
// $.score("hello world", "axl") //=> 0.0
// $.score("hello world", "ow") //=> 0.6
// $.score("hello world", "hello world") //=> 1.0
//
// Tested in Firefox 2 and Safari 3
//
// The Quicksilver code is available here
