 Description: Macro used to add versioning info needed by ROOT to a CMS templated class

 Usage:
    Add the following line to a template class' public declaration area
      CMS_CLASS_VERSION(<number>)

  For classes that have been stored into ROOT files before the addition of the macro, we suggest starting the <number> at 10. This was chosen to be larger than any known number of stored changes to a templated class.
  For new classes that have never been stored, we suggest starting the <number> at 3 (0 and 1 have special meanings to ROOT).
