Describes a persistent version of a class.
A ROOT file contains the list of TStreamerInfo objects for all the class versions written to this file. When reading a file, all the TStreamerInfo objects are read back in memory and registered to the TClass list of TStreamerInfo. One can see the list and contents of the TStreamerInfo on a file with, e.g.,
A TStreamerInfo is a list of TStreamerElement objects (one per data member or base class). When streaming an object, the system (TClass) loops on all the TStreamerElement objects and calls the appropriate function for each element type.

The class ckecksum is used by the automatic schema evolution algorithm to uniquely identify a class version. The check sum is built from the names/types of base classes and data members. The valid range of code is determined by ECheckSum.
This is needed for backward compatibility.
This function must be kept in sync with TClass::GetCheckSum. They are both used to handle backward compatibility and should both return the same values. TStreamerInfo uses the information in TStreamerElement while TClass uses the information from TClass::GetListOfBases and TClass::GetListOfDataMembers.
