Usage of etcd/raft

[Nils Lagerkvist]

I'm trying to follow the documentation of in the raft library in etcd, and I was hoping that someone could review my code.

The example should:

* start a three node cluser

* wait for it to start

* commit one data entry to the cluster

* read the data entry back

If someone have time please check that the cluster node implementation looks sane. 

Also, I don't know how to check that the cluster is ready or that a proposed value has been written. 

In addition, is it safe to fetch the a stored value directly from the node? as there is no consensus. 

The code can be found at: https://gist.github.com/1877fdf922b8b6f8ce35.git

Thanks in advance!

I quickly looked and it seems fine.

In etcd we generate a random ID and wait for that ID to be applied.
