A vector clock implementation.

This module re-exports Data.VectorClock.Simple, which is the fully-featured vector clock library. If you wish to use approximate vector clocks, which are significantly smaller and have bounded size, but are not exact, use Data.VectorClock.Approximate instead.

See Fundamentals of Distributed Computing: A Practical Tour of Vector Clock Systems by R. Baldoni and M. Raynal for an overview of vector clocks.
