Release Notes
-------------
Add unit_test for nemsiogfs library.
The test fully exame the library function as its originally proposed.
The compile of unit_test need to choose apporpriate support libraries based on machine.
-------------
Adjust to NCO format for version v2.2.0

Change History
--------------
 v1.0.0 - Initial Version
 v1.1.0 - Release the read and write order of GFS variables in nemsio files. 
 v2.0.0 - Correct error in write of albedo ('alvsf' component) in routine
          nemsio_gfs_wrfsfc4.  The write of 'alvsf' was inadvertently commented
          out, which resulted in a field of all zereos being written to a nems output
          file. Reorganize directories to better conform to NCO vertical structure.
          New driver script to build code on all WCOSS machines.  Add TKE.
          Create "_slg" versions of routines without p, dp and vvel.
          Remove "_slg" versions and add nopdpvv option to exclude dp, p.
          Use meta data header to decide which fields are read/written.
 v2.0.1 - For relocation code runs on Cray without P, DP, and vvel, Fanglin pass the 
          indicator "nopdpvv" to function 'nemsio_gfsgrd_open' above previous version.
 v2.2.0 - update based on v2.0.1 to include the flux variables and missing surface 
          vaiables, and new functions defined to use these variables. Furhter update 
          of variables may be based on changes in model development.
Implementation Instructions on WCOSS-Phase 1/2
----------------------------------------------
 - cd to appropriate build directory
 - checkout subversion tag: https://svnemc.ncep.noaa.gov/projects/nceplibs/nemsiogfs/tags/v2.0.0
 - cd to the ./src directory
 - type "build.sh" to build library with the Intel compiler.
 - the library and include module will be placed in the following directory structure:

            |
            `--libnemsiogfs.a
            |
            `--include
                  |
                  `--nemsiogfs
                           |
                           `--nemsio_gfs.mod
