parseParams() function written by Todd Resudek for Supersimple.org
Released November 2006

This function will parse any query string parameters into an array of key-value
pairs. 

The purpose is to be able manipulate a page, using variables, without the need
for a server-side technology.

The script runs itself onload, and stores all params into an associative array.
To access a specific value, use params[key]; (eg. alert(params['product']); )
