Very crude example of how to split Audio and pipe it to two different output devices.

Things that are very wrong:

• Audio will potentially crackle if devices have different Sample Rates and formats, need to introduce Converter Nodes.
• Hard coded artificial delay on starting the Output Engines, if delay is removed something (not sure what) is causing output callback to not be called.

People to thank:

• Vlad Gorlov for his RingBuffer class.
• Jasmin Lapalme for this CAPlaythrough rewrite to Swift
• Amateur code monkey Roman Kisil for this poor example
