Automatically link tutorials

[SchettlerKoehler]

As a website user, I want to have links to the tutorials in the documentation so that I can find tutorials matching the topic of the current article. There should be links to the katacoda and to the wiki version of the tutorial. In some situations, it can be a good idea to link to the tutorial search (with predefined parameters) and not to a specific tutorial.

How an article is defined? Is it a current viewing page of documentation or it can be a group of pages?
