Improves document structure and content

o Adds latest pdf
o Improves Appendix (draws styling in main file)
o Adds new graphic of the whole workflow to the appendix
o The introduction is now ordered differently. Complexity and position
  are closer together, why to separate them by identity. This
  is also reflected by the results section. (other sections
  need restructuring)
o Improves the results section. Collects the chunks on top and uses
  the framed environment provided by the open science paper now.
