//Class designed to perform fast on-flight reconstruction of raw data
//without writing it to file and without creation of all aliroot folder 
//structure. This class keeps lists of (raw) digits, RecPoints TrackSegments and 
//RecParticles for one (current) event. In addition, for convinience, it returns 
//pointers to PHOS geometry, Clusterizser, TSMaker and PID maker.
