/**
 * Quarter notes that decellerate. Subclass Note and override getPerformanceData() to take complete
 * control of data actually performed, independent of notation. In this example, each quarter note slows
 * down a little more, like a ritard. Important to understand that a score built this way will not
 * save and load back with this note subclass.
 * 
 * Thanks to Pavlos Marios for prompting this example.
