Generate chords for a given key.
I believe my Theory.allChords function is taking a long time to generate all of
the chord possibilities. I would like to profile this to verify this
assumption. I think I can create a "staging area" for changes and only
regenerate chords when "committing" the options from the "staging area". This
should stress the application less.
TODO: Profile application to find bottleneck.
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."
Define two functions for attempting to return an element in a list that precedes
or succeeds another element.
I prefer having something like Utils.List. Perhaps I will refactor.
