   This namespace contains all C++ wrapper objects for the internal CORSIKA
   data (block/ subblock). This is realized by a set of classes, 
   knowing how to access the binary CORSIKA data.

      \class TBlock
      \brief One CORSIKA data-block, containing 21 sub-blocks.

      This is the main CORSIKA data object. It mirrors the binary 
      block of fortran REAL*4 data
      with a variable size for thinned and not-thinned CORSIKA runs.
      During creation of a TBlock the underlying data is scanned for 
      valid TSubBlock. It is possible to access these TSubBlock using 
      iterators.
