Examples of QuorumPeer

org.apache.zookeeper.server.quorum.QuorumPeer
This class manages the quorum protocol. There are three states this server can be in:
1. Leader election - each server will elect a leader (proposing itself as a leader initially).
2. Follower - the server will synchronize with the leader and replicate any transactions.
3. Leader - the server will process requests and forward them to followers. A majority of followers must log the request before it can be accepted.
This class will setup a datagram socket that will always respond with its view of the current leader. The response will take the form of:
```
 int xid; long myid; long leader_id; long leader_zxid; 
```
The request for the current leader will consist solely of an xid: int xid;
