// Begin(): called every time a loop on the tree starts,

|
// a convenient place to create your histograms.
|
|
// SlaveBegin(): called after Begin(), when on PROOF called only on the
|
|
// slave servers.
|
|
// Process(): called for each event, in this function you decide what
|
|
// to read and fill your histograms.
|
|
// SlaveTerminate: called at the end of the loop on the tree, when on PROOF
|
|
// called only on the slave servers.
