Hi @delirious-lettuce,

This has come up to the top of my backlog to merge. Could you please fix the merge conflict so that I may merge this PR?

Thanks!

@thinkingserious ,

I actually deleted my fork a while ago since I thought this PR was abandoned. I could fork and re-submit a new PR that does the exact same thing but otherwise I'm not sure how to proceed?

[thinkingserious]

A new PR would work, thanks!

[delirious-lettuce]

@thinkingserious ,

Ok, sorry about the mixup! I'll re-submit ASAP.

[thinkingserious]

No worries @delirious-lettuce :)

We are running very behind due to a wonderful Hacktoberfest turn out.

@thinkingserious ,

No problem at all, I can only imagine how hard it would be to go through hundreds (if not thousands!) of pull requests!
