Thank you, @CBroz1! Looks good in overall. Left some small comments.

Hi @tdincer - Merged your PR and fetched from upstream. Do you have time to finish review here today, so we can deploy to codebook tomorrow?

The only remaining item on this is the root_dir / processed_dir issue we discussed verbally. Lmk if you have additional thoughts.

To summarize:

• The previous strategy:
  1. Output function processed returned the first available root if not otherwise specified by the user.
  2. Resulted in errors for projects not in the first available root.
• My current strategy:
  1. Returns None when the output function isn't specified.
  2. When None, chooses the root that aligns with the current project - essentially removing the hardcoding of 'first'

This would be backwards incompatible in the unlikely situation in which someone (a) had multiple roots, with their main project dir not in the first, and (b) expected results to be stored in the first without defining processed function. In this case, the easy solve is to define the output function to point to the first.

@kabilar - Let me know if you have any thoughts on this

Thank you @CBroz1! I'm merging this now but I'll run some tests to check these changes next week.
