Clear some cookies.

        Invoking this method without arguments will clear all cookies.  If
        given a single argument, only cookies belonging to that domain will be
        removed.  If given two arguments, cookies belonging to the specified
        path within that domain are removed.  If given three arguments, then
        the cookie with the specified name, path and domain is removed.

        Raises KeyError if no matching cookie exists.
