Automatic graphical note representation

[aminya]

A custom method for Measure should be defined that uses attributes to fill note fields.
aminya/AcuteML.jl#107

blocked by aminya/AcuteML.jl#130, but the basic code is written:

@aml mutable struct Measure "measure"
    attributes::UN{Attributes} = nothing, "~"
    notes::Vector{Note}, "note"
    @creator begin
        notes = note_graphics(notes, attributes)
    end
end

"""
Finds the graphical representation of a note based on attributes.divisions and note.duration

# Examples
notes = [
Note(pitch = Pitch(step = "G", alter = 0, octave = 5), duration =  1),
Note(pitch = Pitch(step = "G", alter = +1, octave = 5), duration =  1),
Note(pitch = Pitch(step = "B", alter = 0, octave = 5), duration =  1),
Note(pitch = Pitch(step = "A", alter = +1, octave = 5), duration =  1),
Note(rest = Rest(), duration =  4), # Rest
Note(pitch = Pitch(step = "A", alter = 0, octave = 5), duration =  4),
Note(pitch = Pitch(step = "B", alter = 0, octave = 5), duration =  4),
]
MusicXML.note_graphics(notes, Attributes())
"""
function note_graphics(notes, attributes)
    for inote=1:length(notes)

        type = note_graphics_map[actual_duration]
        notes[inote].type = type
    end
    return notes
end

const note_graphics_map = Dict(
    1//256 => "1024th",
    1//128 => "512th",
    1//64 => "256th",

The blocking issue is merged now. It should be possible to fix this.
