Tabs or spaces

Y U USE TABS?
In all seriousness, we should decide if there will be any style guidelines, or if it works, it gets merged. Thoughts?
See the PEP 8.

I think there is no need to establish style guidelines, and anything that works should be merged. The person who merges a pull request has the responsibility to ensure that inconsistent indentation will not be an issue. We certainly learnt our lesson with #53, #55, #56.

That said, if somebody wants to express a different opinion, here's the place.

Seems fine to me, but we'll need to be careful about tab/space mixing.

I think that we should define tab/space because its a syntax element, but
other than that, we could just say whatever, but I think enforcing pep8
(even if not strictly) will be better long term

How about making this more explicit by placing a guideline that the operator should ensure that all indentation is consistent (not mixed)?

[mrhmouse]

I think that requiring consistent indentation throughout a single app or file is reasonable.

I don't think this issue still requires input, but I'm adding it to the documentation milestone and leaving it open to remind us that it should be documented.
