UPDATE:

	(*) ClusterMerge now requires in ClusterMergeAlg pointer
	(*) ClusterMerge does not run ClusterMergeAlg::ProcessMergeAlg() any more. ClusterMergeAlg should have been processed prior to call ClusterMerge::analyze() function.
	(*) In other words, one should just simply attach ClusterMergeAlg pointer to ana_processor and then also pass it onto ClusterMerge instance.
