Reorganizing the document

[CppCXY]

The document was written when version 1.0.0 was released, and many versions have passed since then. Many new features have been released, but they are not mentioned in the document. Additionally, the examples in the document are very basic. Writing documentation is a tiring task, and there is no motivation to improve it. Let's wait until the project reaches 100 stars before considering further improvements.

The project has 100 stars, but I'm currently working full time on the emmylua analyzer, so I'll see if I have time to rewrite the docs early next year, or if there's anyone out there who'd be willing to help me with some of the docs.
