Format the code

[wilsoncheung7]

Just formatted the code, no important changes.

I don't think it's a good idea to commit any .idea files. Also we should agree on a specific formatter as especially max line width is handled differently across formatters and individual settings. Otherwise we will end up in an edit war.

@rbignon, what do you think?

Hello,

Yes, we will not include any IDE specific files for a light python script like doctoshotgun.
