Revoke namespace change

[AntonReinhard]

This PR revokes the namespace changes done before QEDbase.jl 0.2 was released.

Currently based on #25, I will rebase once that is merged.

I've also deleted the ProcessSetup tests since fixing them started taking too long and they are deprecated anyways.

General question since we will now often implement interfaces defined somewhere else (i.e. in QEDbase): I think for clarity it would be a good idea to always use function QEDbase.interface_function() ... end directly, because it makes it clear right there that it's implementing an interface. The other option is having an import QEDbase: interface_function at the start of the file. This, in my opinion, kind of hides the fact that when we have function interface_function() ... end later, it is implementing an interface from QEDbase.

I've done it using QEDbase.interface_function mostly, but not everywhere. If we want to make that a guideline I will go through this pr again and do it in the remaining places.

Thoughts?

As I mentioned somewhere else, I think QEDbase.interface_function is favorable, because of the reasons you already mentioned. Therefore, I agree with making this the guideline.

@AntonReinhard is there a reason, that this is still a draft?

Yes, as I mentioned I will go through again and remove the import QEDbase: ... occurrences. Then I'll mark it ready.

LTFM.
