 This is an implementation of Vivaldi Network Coordinates, a specific NC
-algorithm, with a simple simple interface and few dependencies. Vivaldi
-coordinates are typically used in distributed networking applications, like p2p
-networks. They allow each node in the network to estimate its position in a
-latency space in a distributed way, with no central authority. This enables
-nodes to understand estimated latency to any other node in the system.
