Description

I added a function generate_pdf_export which enables the user to export a pdf which then shows first how many questions where harmonized with the threshhold that was setted and then shows all the harmonizes questions and the percentage to which they matched and lists them in the order where the best matches are on top.
The dependencies that are required for this change is the library fpdf, which i added to the requirement.txt.
