Detailed Description

Concrete implementation of a simple algorithm for clustering of the raw hits registered by the 2D IST sensors. The clustering is done by searching in the 2D sensor plane indexed by row and column id's.

1) Reads all raw hits per ladder (six sensors) and writes into a vector. 2) Starts from the 1st raw hit, and loops over the vector looking for neighboring raw hits (in a sensor area) and do clustering. The found cluster will be filled into a ladder cluster collection. 3) A case-by-case splitting algorithm can be enabled/disabled for the found clusters (here only works for cases with cluster size <= 4).
