public interface ChannelListener

Title: ChannelListener

Description: An interface to listens to incoming messages from a channel

When a message is received, the Channel will invoke the channel listener in a conditional sequence. if ( listener.accept(msg,sender) ) listener.messageReceived(msg,sender);
A ChannelListener implementation MUST NOT return true on accept(Serializable, Member) if it doesn't intend to process the message. The channel can this way track whether a message was processed by an above application or if it was just received and forgot about, a featuer required to support message-response(RPC) calls
