This is my special module intro page.
It works automagically if the post’s slug is configured in a particular way.
First, the slug must be formatted according to a particular formula:
course-slug + "-" + module-slug + "-plan"
Secondly, the post must be within the “Module Intros” category.
If those two things are in place, the intro will show up properly.
In this case, this intro should appear under the “Level One” module assigned to “My Snazzy Course”.
