Test PDFs

This folder contains PDFs for testing purposes and the parse results of the PDFs. Generally there are 3 types of PDFs test setups:

1. Self generated PDFs
2. PDFs which entered public domain or have a otherwise permissive license like Creative Commons SA
3. PDFs where the license is unclear

For (1) and (2) we track the end-result and all transformation steps. For (3) we only track the resulst of some transfomation stages (those who doesn't leak too much of the content)
