--  BigSurObject - This is the top level of the templates. Some of the
--                 data structures will not need the association with
--                 Grid and Variable (They will just be Postscript
--                 files, or in the case of the Photo-CD data, just
--                 slides.)
--
--         MetaData                   - This is a reference to the
--                                      Meta-Data associated with the
--                                      Data file.
--
--         BigSurObject               - This is it! The objective of the
--                                      whole buffalo hunt!
--
--         fileOffSet                 - integer offset within file. This
--                                      is used to 'step over' header
--                                      information and to allow us
--                                      to describe each 'data set' within
--                                      a file storing several data sets.
--
--         storageFormat              - One of a canonical list of 
--                                      storage formats; NDF, CDF, GRIB,
--                                      Fortran etc.
--
