1) Changes to ClusterMergeAlg to work on refining start/end point stuff. Currently works running over a file, but problems occur when re-running over the file with a different cut value. Have been unable to find the source of the problem so far...
2) Minor change to ana_info_struct to add a n_hits variable to the cluster_merge_info struct... n_hits is just the # of hits that belong to that cluster.
3) Included a sample macro that demonstrates the problems outlined in (1)
I have no idea what this is doing.
