cookie parsing with signatures
Cookie header and populate
req.cookies with an object keyed by the cookie
names. Optionally you may enable signed cookie support by passing a
req.secret so it may be used by other middleware.

decodea function to decode the value of the cookie
Parse a cookie value as a JSON cookie. This will return the parsed JSON value if it was a JSON cookie, otherwise it will return the passed value.
Given an object, this will iterate over the keys and call
JSONCookie on each value. This will return the same object passed in.
Parse a cookie value as a signed cookie. This will return the parsed unsigned value if it was a signed cookie and the signature was valid, otherwise it will return the passed value.
Given an object, this will iterate over the keys and check if any value is a signed cookie. If it is a signed cookie and the signature is valid, the key will be deleted from the object and added to the new object that is returned.
