Add lib vs framework article

I really like this short article as an explanation of difference between a library and a framework, and also as an explanation what a framework should do. This would be a good addition to Architecture lecture, but there is no task for it in out repo, so I'm not sure where to put it.

Start by locating the Architecture lecture materials and reviewing the linked article about libraries and frameworks. Done means deciding where the article belongs and adding it to the appropriate lecture content, but the issue does not identify a file or existing task location.
