  \class SOPHYA::PPF_TPointer_IO
  \ingroup BaseTools
  A template utility class with static methods to ease handling of array 
  I/O in PPF streams (POutPersist and PInPersist). It is not intented for
  direct use in user programs, but for writing PPF persistence handler 
  classes (PPersist). 
  The C++ I/O operators POutPersist& << and PInPersist& >> should be defined for
  new types and classes.
