> Some protocols such as Kerberos have a complex layered mechanism.
> Implementing this kind of protocol in one IoHandler is not really easy. It
> usually uses the well-known 'Chain or Responsibility' pattern to implement
> the whole protocol. IoFilter already provides CoR, but It is not really a
> good idea to implement a protocol logic as an IoFilter. We'll implement an
> IoHandler called 'ChainedIoFilter' and provide associated interfaces such as
> IoHandlerCommand and IoHandlerChain to support CoR pattern for protocol
> implementors.
