27// A singleton. This class should be used in the analysis stage to get
28// reconstructed objects: Digits, RecPoints, TrackSegments and RecParticles,
29// instead of directly reading them from galice.root file. This container
30// ensures, that one reads Digits, made of these particular digits, RecPoints,
31// made of these particular RecPoints, TrackSegments and RecParticles.
32// This becomes non trivial if there are several identical branches, produced with
33// different set of parameters.
34//
35// An example of how to use (see also class AliPHOSAnalyser):
36// for(Int_t irecp = 0; irecp < gime->NRecParticles() ; irecp++)
37// AliPHOSRecParticle * part = gime->RecParticle(1) ;
38// ................
39// please->GetEvent(event) ; // reads new event from galice.root
