Return a decoded value from a string representation. Return value can
be any type. This method does nothing in BaseCookie -- it exists
so it can be overridden.

In general, it should be the case that value_encode() and
value_decode() are inverses on the range of value_decode.
[attrs[, header[, sep]]])
Return a string representation suitable to be sent as HTTP headers.
attrs and header are sent to each Morsel's
output() method. sep is used to join the headers
together, and is by default the combination '\r\n' (CRLF).
Changed in version 2.5:
The default separator has been changed from '\n'
to match the cookie specification.
The meaning for attrs is the same as in output().
If rawdata is a string, parse it as an HTTP_COOKIE and add
the values found there as Morsels. If it is a dictionary, it
is equivalent to:
