-//==============================================================================
-// AliAnalysysTask - Class representing a basic analysis task. Any
-// user-defined task should derive from it and implement the Exec() virtual
-// method.
-//==============================================================================
-//
-// A specific user analysis task have to derive from this class. The list of
-// specific input and output slots have to be defined in the derived class ctor:
-//
-// UserTask::UserTask(name, title)
-// {
-// DefineInput(0, TTree::Class());
-// DefineInput(1, TH1::Class());
-// ...
-// DefineOutput(0, TTree::Class());
-// DefineOutput(1, MyObject::Class());
-// ...
-// }
-//
-// An existing data contaner (AliAnalysisDataContainer) can be connected to the
-// input/output slots of an analysis task. Containers should not be defined and
-// connected by the derived analysis task, but from the level of AliAnalysisManager:
-//
-// AliAnalysisManager::ConnectInput(AliAnalysisTask *task, Int_t islot,
-// AliAnalysisDataContainer *cont)
-// AliAnalysisManager::ConnectOutput(AliAnalysisTask *task, Int_t islot,
-// AliAnalysisDataContainer *cont)
-// To connect a slot to a data container, the data types declared by both must
-// match.
-//
-// The method ConnectInputData() has to be overloaded by the derived class in order to
-// set the branch address or connect to a branch address in case the input
-// slots are connected to trees.
-// Example:
-// MyAnalysisTask::ConnectInputData(Option_t *)
-// {
-// // One should first check if the branch address was taken by some other task
-// char ** address = (char **)GetBranchAddress(0, "ESD");
-// if (address) {
-// fESD = (AliESD*)(*address);
-// } else {
-// fESD = new AliESD();
-// SetBranchAddress(0, "ESD", &fESD);
-// }
-// }
-//
-// The method LocalInit() may be implemented to call locally (on the client)
-// all initialization methods of the class. It is not mandatory and was created
-// in order to minimize the complexity and readability of the analysis macro.
-// DO NOT create in this method the histigrams or task output objects that will
-// go in the task output containers. Use CreateOutputObjects for that.
-//
-// The method CreateOutputObjects() has to be implemented an will contain the
-// objects that should be created only once per session (e.g. output
-// histograms)
-//
-// void MyAnalysisTask::CreateOutputObjects()
-//{
- // create histograms
-// fhPt = new TH1F("fhPt","This is the Pt distribution",15,0.1,3.1);
-// fhPt->SetStats(kTRUE);
-// fhPt->GetXaxis()->SetTitle("P_{T} [GeV]");
-// fhPt->GetYaxis()->SetTitle("#frac{dN}{dP_{T}}");
-// fhPt->GetXaxis()->SetTitleColor(1);
-// fhPt->SetMarkerStyle(kFullCircle);
-// }
-//
-// The method Terminate() will be called by the framework once at the end of
-// data processing. Overload this if needed. DO NOT ASSUME that the pointers
-// to histograms defined in CreateOutputObjects() are valid, since this is
-// not true in case of PROOF. Restore the pointer values like:
-//
-//void MyAnalysisTask::Terminate(Option_t *)
-//{
-// fhPt = (TH1F*)GetOutputData(0);
-// ...
-//}
