Define code formatting rules and setup a formatter or the maven checkstyle plugin

[krichter722]

Currently there's a wild mixture of tabs and spaces (4 or 8) being used for indentation (some even mixed in the same file). I'd suggest 4 spaces indentation (no tabs due to incompatibility with mailing lists) for all files (java, XML, etc.) and use checkstyle rather than a formatter. Document everything is HACKING or CONTRIBUTING. I'd be willing to do it, just assign me.

You are welcome to do that!
If you need code change: PR. If you want to change documentation: my idea was to use github wiki for that. There is already development documentation. Feel free to contribute in Wiki as well!

Btw, I'll licence all files which are missing a header (I didn't find one single after superficial search) as described in LICENSE with you name. What copyright year/years should I take (should be the one LICENSE was added to the public repository, right?)?

[krichter722]

I think you need to used different keywords in commits. This is closed, right?

[PhantomYdn]

I guess we can close this. But sometime before release I will reformat spacing.

[krichter722]

The check_style.xml you created is fine. Maybe remove the spaces and enforce indentation at some point.

[PhantomYdn]

Yea... Also will enforce JavaDocs once it will be ready.
