RFC: New repository for code examples in Documentation

[diplopito]

Most of the documents bring code snippets. Considering that full file examples would take a lot of space in the documents and make them complex, a new repository with running examples per main classes would be a useful complement to them. The documentation could make direct reference to them. The users can clone the repository and run the examples in his/her local environment to have fully running demos of the code cited in the docs.
