Small Doc Update for ReportEventStack and Test

[irishgordo]

Proposed Commit Message

• small document update for ReportEventStack explaining post_files
  parameter
• small unit test for test_reporting demonstrating the close of an
  event with optional post_files list

Summary

Hey there, this project is rad! Trying to wrap my head around bits of it here and there, very greenhorn still haha. Thought there might be a slight benefit to a little more documentation surrounding an optional list parameter. Added an additional little test for small additional gain of test coverage and demonstration.

Checklist:

• My code follows the process laid out in the documentation
• I have updated or added any unit tests accordingly
• I have updated or added any documentation accordingly

Also, not entirely sure how to tie Launchpad stuff to GitHub, but for-what-its-worth, I do have a Launchpad account here:

Thanks for the info!
Sorry about the oversight with the CLA Signers File and CLA, pushed up another commit that possesses the change.

Glad I could help, I'm super game to make any adjustments if needed as well with the additional test or doc update too.
Always wanna make sure info and whatnot makes sense haha 😆

Thanks again for the quick response and the approval!
