C# Class Smrf.NodeXL.Algorithms.ClusterCalculator

Partitions a graph into clusters.
Use the Algorithm property to specify the clustering algorithm to use.

Set the PutNeighborlessVerticesInOneCluster property to true to put the graph's neighborless vertices into one cluster.

IMPORTANT NOTE: If PutNeighborlessVerticesInOneCluster is true, CalculateGraphMetrics removes any neighborless vertices from the graph that is passed to it.
