ConsistentHash

class ConsistentHash[T] extends AnyRef

Consistent Hashing node ring implementation.

A good explanation of Consistent Hashing: http://weblogs.java.net/blog/tomwhite/archive/2007/11/consistent_hash.html

Note that toString of the ring nodes are used for the node hash, i.e. make sure it is different for different nodes.
