  + A simple version of the Performance Codec with encode, and decode functions.
* The part object now contains several new methods such as: `part.measures()`, `part.use_musical_beat()`, and others.
* Multiple parts of the same score can now be merged to one even if they contain different divs, call: `partitura.score.merge_parts([p1, p2, ...])`.
