/* COOKIES.JS - JavaScript Cookies Library (version 1.1)
** =====================================================
** Copyright 1999, Richard Scott (version 1.1). All rights reserved.
**   Streamlined Cookie(), Cookie_store(), Cookie_get(), Cookie_del().
**   Removed document parameter from Cookie() constructor function.
**   Removed CookieTable() diagnostic tool.
**   Added explanatory comments.

**   There are several good JavaScript cookie libraries around.
**   One is Bill Dortch's public domain cookie functions
**   (at http://www.hidaho.com/cookies/cookie.txt), and another is David 
**   Flanagan's cookie example in JavaScript: The Definitive Guide, 
**   published by O'Reilly Press. This library combines the best features 
**   of both: The thoroughness of Dortch's cookie functions, and the 
**   object-oriented design of Flanagan's cookie example.
