7// High Level Trigger ITS vertexer
8// This class is a fast version of the off-line AliITSVertexerZ.
9// The two main differences with respect to the off-line vertexer
10// are the splitting of the clusters in phi bins and the filling
11// of local arrays instead of root histograms.

13// Origin: Cvetan Cheshkov, CERN, Cvetan.Cheshkov@cern.ch
