One-line Summary: NCL new version, scripts modified to use grid files for za tool, new runoff modifications,
new README
Files Modified: popdiag.csh, popdiagdiff.csh, popdiagts.csh, mld.ncl, mld_diff.ncl, README.pdf
Files Added: /tool_lib/process_cpl7b_logfiles_fw.awk
             /tool_lib/process_cpl7b_logfiles_heat.awk
	 
Description: 
1. Dave Brown created two new built-in functions in the new version of NCL (6.1.0). Because
of that, he modified mld.ncl and mld_diff.ncl to use them.

2. Runoff is now a module of it's own; therefore, the way the coupler files are written is different, and
the way the diagnostics processed these files had to change. Two new files (see above) are added and a new
option (7b) is listed in popdiag and popdiagdiff for CPL.

3. Because of recent updates, there is a new README file.

One-line Summary: zonal average tool now uses grid files
Files Modified: popdiag.csh, popdiagdiff.csh
Files Added: /tool_lib/zon_avg/grids/gx1v6_grid_info.nc
             /tool_lib/zon_avg/grids/gx3v7_grid_info.nc
	     /tool_lib/zon_avg/grids/tx0.1v2_grid_info.nc
	 
Description: The zonal averaging tool broke for the tx0.1v2 version output because of land
block elimination creating undefined values where mask values used to be. To fix this, we
now invoke the -grid_file option of the za tool so that grid information is gathered from
a pre-made file rather than from the model output. The calls to the za tool within the
popdiag.csh and popdiagdiff.csh scripts have been modified accordingly.

One-line Summary: Updated README for Swift/NCL version
Files Modified: README.pdf

Date: June 14, 2012
One-line Summary: This is the beginning of the NCL/SWIFT version of the diagnostics.
Code origination: The code is a direct copy of /tools/proc_ocn/pop_diag/branches/popdiag/release 
              which is equivalent to /tools/proc_ocn/pop_diag/branch_tags/popdiag_rel_20120117/.
	   
NCL modification:
All plotting scripts were converted to NCL by Dave Brown of CISL as part of the PARVIS project. Only 
changes to plotting scripts were done. The fer_lib and idl_lib are no longer necessary. All reference
to these directories or IDL settings (like IDLCOLOR) have been removed by S. Bates from the main 
diagnostics scripts. 

SWIFT modification:
SWIFT can now be used (if turned on) to parallelize the reading/writing/creation of data used by
the diagnostics scripts. This was done by Sheri Mickelson at Argonne Nat'l Lab as part of the PARVIS
project. A SWIFT README is now included (S. Mickelson) and the original README has been updated 
(S. Bates).
