First release of the exercises for 2022-2023 edition of the course

In this release I provide all of the code for the exercises from last year, I added some documentation and provided some explanations.
All of th exercises work but they are not perfect and some of the solutions could be improved because they are working but maybe are not really up to standard.
For more information about that just check the README.md file, it contains informations about things that I feel that could be done differently.
