SpnegoHandler

```
public interface SpnegoHandler
```
Handler of SPNEGO communication exchange. Communication goes through phases:
1. Client sends initiation token to the server. Token is provided by getInitiationToken()
2. Server responds with updated token. Token is provided through handleTokenFromServer(byte[], sk.ipesoft.d2000.d2japi.SpnegoHandler.ResponseHandler)
3. If responseListener is not null then next update of token is required. Client responds through SpnegoHandler.ResponseHandler.respondWithToken(byte[])
4. If responseListener is null then that was final response from the server and logon confirmation message will follow
