Test failures

[EelcoPeacs]

Several of the test cases provided with the package indicate differences in outcome. Especially the test cases

• prn4
• prn9
• prn13
• prn14
• prn15
• test2
• test3

In these test cases it seems that the Fan-in and Fan-out values have switched places in the structural metrics summery. For the other test cases these values are not present, so it seems like a structural bug

Dived a bit deeper into the history and found that this issue is related to #16 where the bug was fixed that cause the tests to fail. Solution will be to adapt the test reference HTML and XML files.

The test HTML reference files also need to be updated for the changed acknowledgement at the bottom of the files
