- Going to keep all elements in main bits array.
- Improved performance of show/hide all element types.
- Created Bar object (which holds an existing element with type of 'bar'). Will pass in notes to be grouped into chords tomorrow. Based on experience, I'm not at all concerned about redundant data structures or causing the GC to take an extra ms to do its job. Chewing cpu cycles with derived object properties rather than storing values (such as a note's clef) for efficiency also looks good.
