ClusterMagnet ( FGeometryCollection& GeometryCollection,
TArray< int32 >& InOutSelection,
int32 Iterations
)

 Merge neighbors, and neighbors of neighbors (out to the Iterations number) to the selected clusters.
Public function Static bool

ClusterSelected ( FGeometryCollection& GeometryCollection,
