///////////////////////////////////////////////////////////////////////////////
// Macro to setup AliPerformanceTask for 
// TPC performance QA to run on PWG1 QA train. 
//
// Input: ESDs, ESDfriends (optional), Kinematics (optional), TrackRefs (optional)
// ESD and MC input handlers must be attached to AliAnalysisManager
// to run default configuration. 
//
// By default 1 performance components are added to 
// the task: 
// 1. AliPerformanceTPC (TPC cluster and track and event information)
// 2. AliPerformancedEdx (TPC dEdx information)
//
// Usage on the analysis train (default configuration):
// gSystem->Load("libANALYSIS");
// gSystem->Load("libANALYSISalice");
// gSystem->Load("libTPCcalib.so");
// gSystem->Load("libTENDER.so");
// gSystem->Load("libPWG1.so");
//
// gROOT->LoadMacro("$ALICE_ROOT/PWG1/TPC/macros/AddTaskPerformanceTPCdEdxQA.C");
// AliPerformanceTask *tpcQA = AddTaskPerformanceTPCdEdxQA("kFALSE","kTRUE","kFALSE","triggerClass"); 
// 
// Output:
// TPC.Performance.root file with TPC performance components is created.
//
// Each of the components contains THnSparse generic histograms which 
// have to be analysed (post-analysis) by using Analyse() function. 
// Each component contains such function.
