//                          High Level Trigger ITS vertexer
//       This class is a fast version of the off-line AliITSVertexerZ.
//       The two main differences with respect to the off-line vertexer
//       are the splitting of the clusters in phi bins and the filling
//       of local arrays instead of root histograms.
//      
//           Origin: Cvetan Cheshkov, CERN, Cvetan.Cheshkov@cern.ch
