//using Cookie Util Function from Wrox Press Professional Javascript for Web Developers
//Chapter 19 of 2009 edition.  Get, Set, and UnSet are all methods and addressed by
// CookieUtil.get("blah") for example.  Javascript cookie handling stinks and I like this 
//better than all of the other canned cookie managment scripts out there because it uses methods 
// instead of super complicated text parsing.  Cheers.
