Add documentation generation

[blablabla1234678]

We need to support documentation generation. It is not hard based on the JSON file. Each hyperlink and data type can get a section. The format can be MD, HTML, SPA? I think the best way would be SPA which loads the JSON file and displays it as as documentation. What else do we need?

[blablabla1234678]

We need versioning. We need detailed description of each hyperlink and data type.

    const docs = {
        main: {
            type: "Hyperlink",
            method: "get",
            uri: "/",
            response: {

For documentation generation we can use the DocumentationIterator or at least the DocumentationParser.
