public interface Member
The Member interface, defines a member in the group.
Each member can carry a set of properties, defined by the actual implementation.
A member is identified by the host/ip/uniqueId
The host is what interface the member is listening to, to receive data
The port is what port the member is listening to, to receive data
The uniqueId defines the session id for the member. This is an important feature
since a member that has crashed and the starts up again on the same port/host is
not guaranteed to be the same member, so no state transfers will ever be confused
