Hey gang,
thank you for all the help getting this iterface basic working.
mrangel and K.V. in particular, as well as anyone else who offered code to help

here is a working basic youtube player in Quest the only working command is
'test'

API reference

I am still going to be working on some of the other features in the tutorials, like playback speed, progress bar and volume input,
as well as general text input to pass to Quest with ASLEvent calls

I am also going to dig into postMessage() to see if it can help Quest communicate with the YouTube Iframe during video playback.
