Subject: [PATCH]  On branch create-csv  Changes to be committed: modified:  
 hash-files 	Added functionality for csv creation and writing to temp file
 for virtual memory persistence. 	Final write function may do some
 validation checks and then write the temp file to its permanent output path.

Next Steps:
 - Should probably package a logrotate.d conf file as well for the logs as part of the logging feature.
