/**
 * @class AliHLTTPCClusterFinder
 *
 * The current cluster finder for HLT
 * (Based on STAR L3)
 *
 * Basically we have two versions for the cluster finder now.
 * The default version, reads the data pad by pad, and find the
 * clusters as it reads the data. The other version has now been
 * developed to cope with unsorted data. New methods for the unsorted
 * version can  be found at the end of the default one i the source file.
 * Currently the new version is only build to manage zero-suppressed data.
 * More functionality will be added later.
 * 
 * The cluster finder is initialized with the Init function, 
 * providing the slice and patch information to work on. 
 *
 * The input is a provided by the AliHLTTPCDigitReader class,
 * using the init() funktion, and the next() funktion in order 
 * to get the next bin. Either packed or unpacked data can be
 * processed, dependent if one uses AliHLTTPCDigitReaderPacked 
 * class or AliHLTTPCDigitReaderUnpacked class in the 
 * Clusterfinder Component.
 * The resulting space points will be in the
 * array given by the SetOutputArray function.
 * 
 * There are several setters which control the behaviour:
 *
 * - SetXYError(Float_t):   set fixed error in XY direction
 * - SetZError(Float_t):    set fixed error in Z  direction
 *                            (used if errors are not calculated) 
 * - SetDeconv(Bool_t):     switch on/off deconvolution
 * - SetThreshold(UInt_t):  set charge threshold for cluster
 * - SetMatchWidth(UInt_t): set the match distance in 
 *                            time for sequences to be merged 
 * - SetSTDOutput(Bool_t):  switch on/off output about found clusters   
 * - SetCalcErr(Bool_t):    switch on/off calculation of 
 *                          space point errors (or widths in raw system)
 * - SetRawSP(Bool_t):      switch on/off convertion to raw system
 *
 *
 * Example Usage:
 *
 * <pre>
 * AliHLTTPCFileHandler *file = new AliHLTTPCFileHandler();
 * file->SetAliInput(digitfile); //give some input file
 * for(int slice=0; slice<=35; slice++){
 *   for(int patch=0; pat<6; pat++){
 *     file->Init(slice,patch);
 *     UInt_t ndigits=0;
 *     UInt_t maxclusters=100000;
 *     UInt_t pointsize = maxclusters*sizeof(AliHLTTPCSpacePointData);
 *     AliHLTTPCSpacePointData *points = (AliHLTTPCSpacePointData*)memory->Allocate(pointsize);
 *     AliHLTTPCDigitRowData *digits = (AliHLTTPCDigitRowData*)file->AliAltroDigits2Memory(ndigits,event);
 *     AliHLTTPCClusterFinder *cf = new AliHLTTPCClusterFinder();
 *     cf->SetMatchWidth(2);
 *     cf->InitSlice( slice, patch, row[0], row[1], maxPoints );
 *     cf->SetSTDOutput(kTRUE);    //Some output to standard IO
 *     cf->SetRawSP(kFALSE);       //Convert space points to local system
 *     cf->SetThreshold(5);        //Threshold of cluster charge
 *     cf->SetDeconv(kTRUE);       //Deconv in pad and time direction
 *     cf->SetCalcErr(kTRUE);      //Calculate the errors of the spacepoints
 *     cf->SetOutputArray(points); //Move the spacepoints to the array
 *     cf->Read(iter->fPtr, iter->fSize ); //give the data to the cf
 *     cf->ProcessDigits();        //process the rows given by init
 *     Int_t npoints = cf->GetNumberOfClusters();
 *     AliHLTTPCMemHandler *out= new AliHLTTPCMemHandler();
 *     out->SetBinaryOutput(fname);
 *     out->Memory2Binary(npoints,points); //store the spacepoints
 *     out->CloseBinaryOutput();
 *     delete out;
 *     file->free();
 *     delete cf;
 *   }
