CausalDemo

java.lang.Object
- org.jgroups.demos.CausalDemo

All Implemented Interfaces:

java.lang.Runnable
```
public class CausalDemo
extends java.lang.Object
implements java.lang.Runnable
```
Simple causal demo where each member bcast a consecutive letter from the alphabet and picks the next member to transmit the next letter. Start a few instances of CausalDemo and pass a paramter "-start" to a CausalDemo that initiates transmission of a letter A. All participanting members should have correct alphabet. DISCARD layer has been added to simulate lost messages, thus forcing delaying of delivery of a certain alphabet letter until the causally prior one has been received. Remove CAUSAL from the stack and witness how FIFO alone doesn't provide this guarantee.
