Acknowledgements

We would like to thank the tutors for solving our doubts and helping us to overcome difficulties, and also the teachers who taught us the lessons that allowed us to develop this project.

We are also grateful to the flatmates of Lorea, who dealt with us during the long hours of hard work. A special mention to the delivery service of Riya Doner Kebab Pizzeria, that arrived on time and saved us from starvation in the last hours invested in this project.
