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