GitLab

Report some typos from docker run -p 8888:8888 -it -e DISPLAY=:0 -v /tmp/.X11-unix:/tmp/.X11-unix -v /Users/sebastien/Documents/Formations/GettingStartedCpp:/home/non_root_user/Formation/Cpp  --cap-drop=all formation_cpp:latest (they were 'lost' follwoing the splitting of one notebook in half).

Remove semicolon at the end of function declaration, and explains why it is required to add a semicolon at the end of a struct

- The image is derived from continuumio/miniconda3 rather than Ubuntu (maybe it is not the right call - no clue one way or another, but we probably have shave off a bit of space. The miniconda one is apparently base on Debian).
- The project is no longer cloned from gitlab, but is rather read from the host (the command line is therefore a bit longer and is documented in the README). The reason for doing so is that the image is lighter and fork may build their own image from their actual master branch rather than silently taking the one from the main project.

I have also removed several lines that seems to add nothing; maybe I was wrong on some of these calls.

The terminal where the `run` command is run is no longer silent; I don't know what triggered the difference here.

String view notebook: one correction, and the copyright notice has been modified as it is entirely new content.

Types notebook: add the possibility to declare std::string from string litterals with 's' suffix (I learned that while preparing string view notebooks).

Rewrite slightly the constexpr section, and add the metaprogramming Fibonacci implementation in the adequate notebook.

Create a new notebook in procedural to discuss static and constexpr. The static part was lifted from the notebook in ibject programming in which it was originally introduced.
