Class description
Opaque type of clips being played by an audio-engine. There are two subclasses provided:

•	static-audio-clip, constructed by <static-audio-clip> or play-static-audio-clip
•	streaming-audio-clip, constructed by <streaming-audio-clip> or play-streaming-audio-clip

Clip objects are transient. They get disposed and invalidated by the controlling audio-engine when their playback finishes or is stopped. The play-clip, pause-clip, and stop-clip words control playback of individual clips. play-clips, pause-clips, and stop-clips synchronize the playing, pausing, or stopping of multiple clips.
