Aftermath for SIGIR2019 branch

While the state at the SIGIR2019 submission is captured in another tag, some work had been done since that. I can't be anything major but there were changes in my local working copy. Those are being tagged here. This will be the last commit on SIGIR2019 stuff. Also note that further development happens at https://github.com/JULIELab/trec-pm.

Code state for the submission to SIGIR19

This is less a release than just a tag. It points to the state of the project for the SIGIR19 submission. It is not cleaned up or throroughly documented. This is mainly a reference for reproducability, if required later on.

v2.0.0

This release contains all the code used by the hpi-dhc group in the TREC-PM 2018 track.
The processing and indexing of the PubMed Literatur and the extra ASCO/AACR abstracts have been done via UIMA and JCoRe, the clinical trials have been indexed with the framework code. All indexing was done into an ElasticSearch 5.4.0 instance.
