Invert diatonic/chromatic does not do what is expected #51

Closed hanshoglund closed 4 years ago

-- Solve by just renaming:
--   invert => invertChromatic
--   (invertChromatic o . invertDiatonic o) => invertDiatonic o

>>> invertPitches c [c,d,eb,fs::Pitch]
[c,bb_,a_,gb_]
>>> 
>>> invertDiatonic c [c,d,eb,fs::Pitch]
[c,b_,ab_,gs_]
>>> (invertDiatonic c . invertChromatic c) [c,d,eb,fs::Pitch]
[c,b_,as_,gb_]
