JFugue 8. Realtime Player

Most of the time we will use the Realtime Player.

We will use this player, in most cases, rather than the one from Player class since it leads to smoother interactions, as audio playing does not block the JavaFX thread. Notice the text immediately follows start of audio, rather than the end of audio. Also the audio start and end should be smoother (no clicks).

We override the stop() method to close the player when the program is closed.
