// A helper object for the generic readMessageContentDecoded method
// implementation. The mail::autodecoder() superclass handles the actual
// decoding task. The decoded() method forwards the decoded data to the
// original application callback object.
//
// This helper object also conveniently subclasses mail::callback::message,
// nicely forwarding the retrieved MIME content to mail::autodecoder.
// It is dynamically allocated, and after its success() or fail() method is
// invoked, the message is obediently passed along to the original
// callback function, and afterwards this object destroys itself.
