Notes on ECCO v4 
========================================================
The note should be in the following format:
Timestampe (yyyy/mm/dd) 
C For code updates
I For Changes  

Example:
20140430
C Split ABC cost to time-mean and time variable parts.
I Reduce XYZ multiplier from 25 to 1. 

20140917
C Split climatology TS costs to time-mean and mean seasonal
C parts. Remove the 0.1 scaling factor to wind stress errors. 
C Correct the bug of zero total cost (fc) in costfunction file.

20140917
C Remove the obsolete file ecco_cost_final.F.trash.

20141203
C Commit V4 Revision 2 setup (r009a).

20150324
C Implement cost-split formuation for climatology, SST, SSS, and 
C profiles costs on the newest code from the 
C CVS main branch (checkpoint65j). 

20151207
C The changes are based on the code downloaded on 11/10/2015 from 
C the main CVS branch. The changes are split profile cost to 
C sample-mean and sample-anomaly parts, implement a separate 
C subroutine to compute global mean costs (ssh, obp, etc.),
C add an alternative proxy cost formulation to compute the sea-ice
C proxy costs, and a few minor changes. For details, see readme.txt 
C in code/.  

20170105  
C Add a document about converting binary output to netCDF, as
C well as interpolating model output from V4 grid to 0.5
C degree grid and converting to netCDF afterwards.

20170504  
C Update code and input directories to be consistent
C with the code (checkpoint66g) in the main repository.

20190423  
C Add an updated ecco_cost_init_barfiles.F
C with a minor bug fix.

20190514  
C Add a safety check to profiles_init_fixed.F and 
C increase numlists in DIAGNOSTICS_SIZE.h
C with a minor bug fix.
