Replace tabs with spaces

[IQAndreas]

Some parts of the code use tabs and others use spaces.

This is fine when most editors use 4 spaces per tab, but since GitHub insists on using 8 spaces per tab, it throws off the formatting entirely (silly GitHub, tabs are for gits).

I don't remember why I recommended using spaces instead of tabs (that GitHub formatting reason is a poor reason). I'm always pro-tabs. :(

In fact, I don't even remember opening this issue. Am I going crazy?

Well I'd argue that spaces are better on projects which involve many people, since they could easily have their IDEs set up differently, and next thing you know you end up with a project that has 4 spaces for a tab in some places, 2 in others, etc. It's for consistency more than anything else.

Or just add a part to the README for this project about saying which rule this project follows. Either way, you get the consistency that makes for more readable code.
