sealed abstract class VersionVector extends Serializable

Representation of a Vector-based clock (counting clock), inspired by Lamport logical clocks.

   1) Leslie Lamport (1978). "Time, clocks, and the ordering of events in a distributed system". Communications of the ACM 21 (7): 558-565.
   2) Friedemann Mattern (1988). "Virtual Time and Global States of Distributed Systems". Workshop on Parallel and Distributed Algorithms: pp. 215-226

Based on akka.cluster.ddata.VersionVector.

This class is immutable, i.e. "modifying" methods return a new instance.

    Compare two version vectors.

    Compare two version vectors. The outcome will be one of the following:

    1. Version 1 is SAME (==)       as Version 2 iff for all i c1(i) == c2(i)
2. Version 1 is BEFORE (<)      Version 2 iff for all i c1(i) <= c2(i) and there exist a j such that c1(j) < c2(j)
3. Version 1 is AFTER (>)       Version 2 iff for all i c1(i) >= c2(i) and there exist a j such that c1(j) > c2(j).
4. Version 1 is CONCURRENT (<>) to Version 2 otherwise.
