A set of functions that eases the pain of using cookies.

Usage: 
WM_setCookie('name', 'value'[, hours, 'path', 'domain', secure]); 
where name, value, and path are strings, and secure is either true or null. Only name and value are required. Note: hours can be either a number of hours until the cookie expires or a GMT-formatted date string such as 'Fri, 13-Apr-1970 00:00:00 GMT'. 

WM_readCookie('name'); 
Returns the value associated with name. 

WM_killCookie('name'[, 'path', 'domain']); 
Remember that path and domain must be supplied if they were set with the cookie.
