24// A singleton. This class should be used in the analysis stage to get
25// reconstructed objects: Digits, RecPoints, TrackSegments and RecParticles,
26// instead of directly reading them from galice.root file. This container
27// ensures, that one reads Digits, made of these particular digits, RecPoints,
28// made of these particular RecPoints, TrackSegments and RecParticles.
29// This becomes non trivial if there are several identical branches, produced with
30// different set of parameters.
31//
32// An example of how to use (see also class AliPHOSAnalyser):
33// for(Int_t irecp = 0; irecp < gime->NRecParticles() ; irecp++)
34// AliPHOSRecParticle * part = gime->RecParticle(1) ;
35// ................
36// please->GetEvent(event) ; // reads new event from galice.root
