Please make this a squash and merge when done. We don't need a merge commit here as the history is kinda messy.

@mammuth you can also do this locally on your branch before opening the PR: https://stackoverflow.com/questions/5189560/squash-my-last-x-commits-together-using-git

Of course. We just squash it with the shiny new GitHub squash-before-merge-button.

@mathiasquintero I also removed the old linked Pods_TUM_Campus_app.framework, and the second referenced group "TUM Campus App" in the last commit, since that led to errors after merging the master back into my branch. As far as I see, those are obsolete?
(That's also the reason why the Travis build failed).

I could imagine that I need some further fine-tuning when the merge is done.

The current tests are not that meaningful right now, I will write some more later (#57)

Just for the curious reader:
The build currently fails, because Travis is not exporting the set environment variables to the build machine:

"Travis CI makes encrypted variables and data available only to pull requests coming from the same repository. These are considered trustworthy, as only members with write access to the repository can send them."

https://docs.travis-ci.com/user/pull-requests#Pull-Requests-and-Security-Restrictions
Corresponding open issue: travis-ci/travis-ci#1946

I'm going to squash and merge.

Since there are some changes to the project configuration etc, I checked out this branch into a new directory and tested whether it broke something for "normal" usage (building/running the app); it seems to work. However, if one of you @mathiasquintero or @TheZoker are faced with some issues due to my changes, just drop me a line!
