Pushed new branch T22618-PCA-example.

I fixed a bug in the MITK point list widget when implementing the example. Thus I need a differential revision (only for commit c1784ad9ced3845589077d6373557933988fba14). How do I request a review in differential?

@franza Did you already install arcanist? [1]

When you install PHP, ensure that you install the latest PHP 5.x, not PHP 7.x.
When arc is installed and configured, it is as simple as executing arc diff in your branch. [2]

Let me know if you need further assistance.

Oh and see also [3] for detailed instructions on how to install PHP and how to incorporate your favorite editor into the arc workflows.
