The Init() function is called when the selector needs to initialize a new tree or chain.
Typically here the branch addresses and branch pointers of the tree will be set. It is normally not necessary to make changes to the generated code, but the routine can be extended by the user if needed. Init() will be called many times when running on PROOF (once per file to be processed).

This function is called at the first entry of a new tree in a chain.
Reimplemented from TSelector.
Definition at line 136 of file TSelectorEntries.cxx.
The Process() function is called for each entry in the tree (or possibly keyed object in the case of PROOF) to be processed.
The entry argument specifies which entry in the currently loaded tree is to be processed. It can be passed to either TSelectorEntries::GetEntry() or TBranch::GetEntry() to read either all or the required parts of the data. When processing keyed objects with PROOF, the object is already loaded and is available via the fObject pointer.
This function should contain the "body" of the analysis. It can contain simple or elaborate selection criteria, run algorithms on the data of the event and typically fill histograms.
The processing can be stopped by calling Abort().
Use fStatus to set the return value of TTree::Process().
The return value is currently not used.
