Investigate modification to LatestFileInPath Function to improve reliability

Consider indexing the log files in the folder and pick out the actual latest, not just the latest write time in the unexpected event that a log entry is written to an earlier log file. This might be especially important if we rewrite the log file to correct errors.

This is related the to aaLogPathManager discussion in #26. The idea is aaLogPathManager would index the files and, as mentioned above, potentially take corrective action.
