Static class to handle COOKIES

        ARGUMENTS
            $name          String with cookie name (cannot be empty)
            $value         String with cookie value
            $expire      The time (expressed as a Unix timestamp) when the cookie is set to expire.
                            If set to 0, it'll expire at the end of the session (when the browser closes)
                            To avoid having to deal with Unix-timestamp values, more specialized methods, such as setDays(), are also provided in this class.                        
            $domain     [OPTIONAL] Site's domain name (such as "example.com"); if missing, the domain is inferred from the server variable "SERVER_NAME"
            
        RETURN VALUE: If output exists prior to calling this function, this function will fail and return FALSE;
            if it successfully runs, it will return TRUE.  (This does NOT indicate whether the user accepted the cookie.)
