Detailed Description

Track Prohibit algorithm: if the angle between the direction of a cluster (end-start) and the line connecting the cluster's start point and the start point of t a second cluster is too large, then probihit merging between the two clusters. The first cluster needs to be a "good" and "large" cluster algorithm has performed
