class AliITSOnlineSPDphys

Author: Henrik Tydesjo
Interface class to the containers of an online scan.
Directly connected to a TFile with all containers.
Handles reading and writing of this TFile. Hitmaps are
stored in this file (AliITSOnlineSPDHitArray).
Also some general information is stored
(AliITSOnlineSPDphysInfo).
