class AliITSOnlineSPDscan

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 and information on nr of events with hits
is stored in this file (AliITSOnlineSPDHitArray and
AliITSOnlineSPDHitEvent). Also some general
information is stored (AliITSOnlineSPDscanInfo).
When switching between different steps of the scan,
the previous step is automatically stored on the file.
With this scheme there is no risk of running out of
memory.
