Add example output as screenshot and/or to Readme.md doc

[zephans]

This looks like a promising project, but I don't want to invest effort trying every tool to get the custom parsed output I need.

In my specific case I'm looking to parse 45 .fpr files into single csv/Excel file with issue counts by priority. Seeing sample output would help me see how close this project is to my needs. For more specifics see Stack Overflow post converting 45 fortify fpr files to csv buildfolder,projectname,critical,high

Thanks!
