While I did change a lot of functionality, I also ran `elm-format` across the
codebase, which makes these changes a bit noisy.
Here is the TL;DR:
- Properly support chord inversions
- Ensure that the piano styling changes dynamically when I change the variables
like `naturalWidth`
- Add start and end notes to define the size of the piano and which chords we
create
- Support elm-format and run it across entire project
- Debug Misc.comesBefore
- Introduce a ChordInspector and debugger
TODO: Ensure that we only generate chords where all of the notes can be rendered
on the displayed keys.
TODO: Add preferences panel, so that I can do things like "Practice blues chords
in C and E with chord substitutions."

Supporting Play/Pause events, and Increase/Decrease tempo.
TODO: Convert milliseconds to BPM

First of all, Elm's purity is beautiful. I think every language should model
their error messages and develop experience after Elm. If I didn't have to
download packages, I don't think I would need an internet connection to
troubleshoot my program's errors. This is how helpful I find the compiler.
Now that that's out of the way, here's what I've changed since we've last
corresponded:
- Use Elm's Browser.element to create a reactive application with state
- Write a function to generate all of the chords about which CDS knows
- Move some code out of Main.elm into other modules
- Depend on List.Extra, Random, Random.Extra
What's left:
- Lots of work
- Instead of clicking a button to show a new chord, use a timer
- Add mobile-first styling (probably add TailwindCSS)
- Persist settings in LocalStorage (and then eventually create user accounts)
- Allow users to curate the list of chords they're interested in practicing
- Deploy the website and dogfood it
Unknowns:
- How can I handle tempo? I don't expect setInterval to be enough (maybe it
is)...

Initialize an Elm application to build a MVP for the Chord Drill Sergeant
application. There isn't much to see at the moment. I'm just sketching
ideas. More forthcoming...
