Introduce PDELab Recipes
Introducing PDELab Recipes as a collection of short example codes demonstrating specific features of PDELab.
Behind the scenes, each example is a short but complete program registered as a test, and therefore part of CI. This should prevent bit rotting and motivate contributors to update the affected recipes whenever a breaking change occurs.
To the user, relevant snippets are shown as part of a doxygen page, accompanied by a brief explanation. (Access to the full code is possible as well via doxygen)
Further recipes will be added over the next few weeks once this is merged.
Depends on !406 (merged) .
