[5pt] Add error scan across logs

[RobHanna-NOAA]

Add to the bottom of post processing, this command.

grep -H -r -i -n "error" ./logs/ > $outputDestDir/all_errors_from_logs.log

There are some errors that are perfectly legitimate but worth reviewing for each fim run (all sizes) such as 'Will not test for outlet backpool error in branch zero.'

The biggest purpose for this tool is that it is hard to find errors in any post processing log files.
