- All Implemented Interfaces: 
- java.io.Serializable, java.util.Map<K,V>, ChannelListener, RpcCallback, Heartbeat, MembershipListener
- public class ReplicatedMap<K,V> 
- extends AbstractReplicatedMap<K,V>
All-to-all replication for a hash map implementation. Each node in the cluster will carry an identical
 copy of the map.
 This map implementation doesn't have a background thread running to replicate changes.
 If you do have changes without invoking put/remove then you need to invoke one of the following methods:
 
 - replicate(Object,boolean)- replicates only the object that belongs to the key
- replicate(boolean)- Scans the entire map for changes and replicates data
theboolean value in the replicate method used to decide
 whether to only replicate objects that implement the ReplicatedMapEntry interface
 or to replicate all objects. If an object doesn't implement the ReplicatedMapEntry interface
 each time the object gets replicated the entire object gets serialized, hence a call to replicate(true)
 will replicate all objects in this map that are using this node as primary.
 
REMEMBER TO CALL breakdown() or finalize()
 when you are done with the map to avoid memory leaks.
 TODO implement periodic sync/transfer thread
 TODO memberDisappeared, should do nothing except change map membership
       by default it relocates the primary objects
