NEW. Added abjad.VoiceNumber(n=None) indicator.
bc37259 
Set n to 1, 2, 3, 4 or none. Models LilyPond ``\voiceOne``,
``\voiceTwo``, ``\voiceThree``, ``\voiceFour``, ``\oneVoice`` commands.

    def make_staff():
        staff = abjad.Staff()
        voice_1 = abjad.Voice("g'8 a' b' c''")
        command = abjad.VoiceNumber(n=1)
        abjad.attach(command, voice_1[0])
        voice_2 = abjad.Voice("e'8 f' g' a'")
        command = abjad.VoiceNumber(n=2)
        abjad.attach(command, voice_2[0])
        container = abjad.Container([voice_1, voice_2], simultaneous=True)
        staff.append(container)
        voice = abjad.Voice("c''4 a'")
        command = abjad.VoiceNumber()
        abjad.attach(command, voice[0])
        staff.append(voice)

    >>> staff = make_staff()
    >>> string = abjad.lilypond(staff)
    >>> print(string)
    \new Staff
    {
        <<
            \new Voice
            {
                \voiceOne
                g'8
                a'8
                b'8
                c''8
            }
            \new Voice
            {
                \voiceTwo
                e'8
                f'8
                g'8
                a'8
            }
        >>
        \new Voice
        {
            \oneVoice
            c''4
            a'4
        }
    }

The abjad.VoiceNumber indicator is contexted at the level of
abjad.Voice. Use abjad.get.effective() to get the abjad.VoiceNumber
indicator in effect for any leaf:

    >>> for leaf in abjad.select.leaves(staff):
    ...     command = abjad.get.effective(leaf, abjad.VoiceNumber)
    ...     print(f"{leaf}, {command}")
    Note("g'8"), VoiceNumber(n=1)
    Note("a'8"), VoiceNumber(n=1)
    Note("b'8"), VoiceNumber(n=1)
    Note("c''8"), VoiceNumber(n=1)
    Note("e'8"), VoiceNumber(n=2)
    Note("f'8"), VoiceNumber(n=2)
    Note("g'8"), VoiceNumber(n=2)
    Note("a'8"), VoiceNumber(n=2)
    Note("c''4"), VoiceNumber(n=None)
    Note("a'4"), VoiceNumber(n=None)

Closes #1135.
