Condensed Tree View split assign most points into noise reduce hitrate #6

This is how condensed tree works in hdbscan

@kingauthur is assigned to this task, so far it works greatly interactive with hidden cluster structure: image

Two interaction has been created:

However, every split also assigns many points into the noisy cluster (cluster 0 which is grey). So the precision is high but the hitrate is pretty low because many points belong to that leaf fall into cluster 0.

This issue needs to be solved by adding adjustable magnet feature for an arbitrary cluster to cure the low hitrate issue.
