Add the LaTeX file of the presetation

Still need to finish some slides and add some figures, but the bulk of the
presentation is already coded. Didn't compile yet (waiting for figures),
so there is probably a lot of small mistakes from coding typos going to
fix this soon.
Prestentation.tex compiled

Compiled the presentation.tex. Need to do some ajustments on the K&E-Z
slide and generate what is missing on the other slides.
