Hoorah! Finally made it through the course! On the other hand, I also
updated the `concat-asset-folder` function to accept multiple arguments
representing the directory hierarchy instead of a separator.
I also forget to add the additional solutions from the Exercism
exercises. Whoops...
I'm also getting used to storing code in random places. Time to change
that habit a little bit by storing them in my notebook, instead.
Nothing wrong with that, yeah?!
I just realized they're just another category of notes. Not much
deviation from the "traditional" notes aside that they're isolated from
all of the notes. It is better to store them under one umbrella than
making a new category of notes. It also makes for a quicker reference
since some of them mostly go through them first.
