DOC: document Cluster's user API
Some stuff you can do:
val node = Cluster(system)
node.registerListener(new MembershipChangeListener {
def notify(currentMemberRing: SortedSet[Member]) {
..
}
})
val membershipStatus = node.status // JOINING, UP, EXITING, LEAVING, REMOVED, DOWN
if (node.convergence.isDefined) { .. } // do we have cluster ring convergence?
if (node.isLeader) { .. } // is this node the leader?
if (node.isAvailable) { .. } // is this node currently considered available?
if (node.failureDetector.isAvailable(otherNodeAddress)) { .. } // is the other node available?
val likelyhoodBeingDown = node.failureDetector.phi(otherNodeAddress) // how likely is it that he is down?

I'll add a first API/usage description of the membership part when I have implemented the new way of subscribing to membership changes (instead of callback listeners). Before that there is no sensible API to use.

First part for membership https://github.com/akka/akka/pull/651
First part merged to master. Closing this ticket, since it too wide. Will document as features are added, or by adding smaller doc tickets.
