All Elements in a segment start at the same tick. The Segment can store one Element for
each voice in each staff in the score. It also stores the lyrics for each staff.
Some elements (Clef, KeySig, TimeSig etc.) are assumed to always have voice zero
and can be found in _elist[staffIdx * VOICES];
Segments are children of Measures and store Clefs, KeySigs, TimeSigs,
BarLines and ChordRests.
