Auto-generate student profiles

[xhluca]

We can use jekyll-datapage-gen.

We can use a boolean to specify which users to generate a profile for. This way, every student can have their own profile without having to create their own markdown file, but also can opt out. We can use the filter function.

An alternative is to have a python function that generates a user's default markdown page using jinja; this function can be called from the existing automation, also based on the opt-in/opt-out boolean. Would be worth evaluating both options.
