Detailed Description

Hierarchical Clustering class. Performs single linkage clustering

         Matrix<double> distance = get_distance_matrix();
      linkage.cluster(distance);
      // Draw clustering tree.
      Draw<double, int> draw(features, labels, "linkagetree.graph");
      linkage.breadth_first_traversal(draw);

ClusterImportanceVisitor

once the clustering has taken place. Information queries can be made using the breadth_first_traversal() method and iterate() method

template<class Functor>
void breadth_first_traversal	(	Functor &	tester	)

Perform breadth first traversal of hierarchical cluster tree

template<class T, class C>

CorrelationVisitor

template<class Functor>
void iterate	(	Functor &	tester	)

Visit each node with a Functor in creation order (should be depth first)

void save	(	std::string	file,
		std::string	prefix
	)

save to HDF5 - defunct - has to be updated to new HDF5 interface
