Chord thoughts

[judddanby]

Here's below the equivalence of the chords in the library:

C∆7 = C∆
C∅ = C∅7 = C-7b5
C7b5 = C7#11
C7#5 = C7b13
C9b5 = C9#11
C7b9b13 = C7b9#5
C7b9b5 = C7b9#11
C11 = C7sus

That's about 9 chords that could be removed from the chord library if they can be added instead as preference in the app option setting (just like "m" or "-" for minor chords)

Some of these are not really equivalent. For example, #11 allows for 5 to be included in a voicing, but b5 directs the player not to.
