Arthur DANJOU f4120eabdf Add initial solution files for Rustlings exercises and quizzes
- Created empty solution files for various exercises in strings, modules, hashmaps, options, error handling, generics, traits, lifetimes, tests, iterators, smart pointers, threads, macros, clippy, conversions, and quizzes.
- Each solution file contains a main function with a comment indicating that it will be automatically filled after completing the exercise.
- Added a README.md file to provide information about the solutions and their purpose.

# Macros
Rust's macro system is very powerful, but also kind of difficult to wrap your
head around. We're not going to teach you how to write your own fully-featured
macros. Instead, we'll show you how to use and create them.
If you'd like to learn more about writing your own macros, the
[macrokata](https://github.com/tfpk/macrokata) project has a similar style
of exercises to Rustlings, but is all about learning to write Macros.
