'Chain of Responsibility' pattern support for IoHandler
-------------------------------------------------------

Key: DIRMINA-137
URL: http://issues.apache.org/jira/browse/DIRMINA-137
Project: Directory MINA
Type: New Feature
Reporter: Trustin Lee
Assigned to: Trustin Lee
Fix For: 0.9


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 p
rotocol implementors.
