39// A singleton. This class should be used in the analysis stage to get
40// reconstructed objects: Digits, RecPoints, TrackSegments and RecParticles,
41// instead of directly reading them from galice.root file. This container
42// ensures, that one reads Digits, made of these particular digits, RecPoints,
43// made of these particular RecPoints, TrackSegments and RecParticles.
44// This becomes non trivial if there are several identical branches, produced with
45// different set of parameters.
46//
47// An example of how to use (see also class AliPHOSAnalyser):
48// for(Int_t irecp = 0; irecp < gime->NRecParticles() ; irecp++)
49// AliPHOSRecParticle * part = gime->RecParticle(1) ;
50// ................
51// please->GetEvent(event) ; // reads new event from galice.root
