### Echo client example
```js
var mc = require('minecraft-protocol');
var client = mc.createClient({
host: "localhost", // optional

password: "12345678", // online-mode=true servers
});
client.on(0x03, function(packet) {
// Listen for chat messages and echo them back.
if (packet.message.indexOf(client.session.username) !== -1) return;
client.write(0x03, {
message: packet.message,
});
});
```

### Test Coverage
```
client
✓ pings the server (6164ms)
✓ connects successfully - online mode (2527ms)
✓ connects successfully - offline mode (1902ms)
✓ gets kicked when no credentials supplied in online mode (3720ms)
✓ does not crash for 10000ms (11731ms)
mc-server
✓ starts listening and shuts down cleanly
✓ kicks clients that do not log in (103ms)
✓ kicks clients that do not send keepalive packets (104ms)
✓ responds to ping requests
✓ clients can log in and chat (43ms)
✓ gives correct reason for kicking clients when shutting down
