Generate a practical error summary to check our output

[pmathiot]

Add exp and variable name in the error line:

            for file in tqdm(exp_files):
                ctag=' exp: {:10}, var: {:15} : '.format(experiment_name,file.split('_')[0])

then for all the relevant error messages:

f.write(' - ERROR: '+ctag+' ...

then

grep ERROR ismip6/compliance_checker_log.txt  > error_summary.txt

output:
