/*
CanSetCookies()
written by Matt Pressnall 10/24/03
What does it do?
Lets you know if a user can set cookies on their local computer -- only works if they have JS turned on. Duh.
How do I use it?
<script src="/js/standardFunctionality/CanSetCookies.js"></script>
<SCRIPT LANGUAGE="JavaScript">
var canSetCookies = CanSetCookies();
</SCRIPT>
It will return true if it's true or false if it is false.

var end = document.cookie.indexOf(";",len);
if (end == -1) end = document.cookie.length;
