19// Implementation of the HLT ITS clusterer class
20// The class derives from AliITSclustererV2.
21// There is one new method added which allows to read ITS raw data
22// and store the clusters in a tree without using runloaders.
23// In this case, the labels filling is skipped.
24// Origin: Cvetan Cheshkov, CERN, Cvetan.Cheshkov@cern.ch
