*   RBBI data formats  Includes
*
*                          Structs that describes the format of the Binary RBBI data,
*                          as it is stored in ICU's data file.
*
*      RBBIDataWrapper  -  Instances of this class sit between the
*                          raw data structs and the RulesBasedBreakIterator objects
*                          that are created by applications.  The wrapper class
*                          provides reference counting for the underlying data,
*                          and direct pointers to data that would not otherwise
*                          be accessible without ugly pointer arithmetic.  The
*                          wrapper does not attempt to provide any higher level
*                          abstractions for the data itself.
*
*                          There will be only one instance of RBBIDataWrapper for any
*                          set of RBBI run time data being shared by instances
*                          (clones) of RulesBasedBreakIterator.
