// These are the default template declarations for the HDF5 I/O
// template functions needed by T objects for binary IO.  The default
// implementations use the linearOut/linearIn/size functions of the
// T template classes to provide non-portable binary IO.
//
// A user can add their own template specializations for
// portable binary IO abilities.
//
// To use this header, a user includes this file first, then
// decalres their template specializations, then includes the CH_HDF5.H
// header file.
