Add Jenkins script

---

In the project directory create the run_jenkins.sh file with the following content:

#!/bin/bash

virtualenv venv
source venv/bin/activate
pip install -r requirements.txt
pytest

Make it executable by running:

chmod +x run_jenkins.sh

Commit it to the git repository and push it out.

Then click on "Build Now" on the Jenkins UI.

It should build successfully now.
