Retire the `examples/` folder?

It occurs to me that the examples/ folder isn’t serving much of a purpose anymore, and we may do better to retire it. I certainly don’t want to maintain it if it’s never used.

The example scripts are not packaged in the distribution, nor are they referred to in the documentation.

$ ls -1
adjust_tuning.py*
beat_tracker.py*
estimate_tuning.py*
hpss_beats.py*
hpss.py*
'LibROSA audio effects and playback.ipynb'
'LibROSA demo.ipynb'
onset_detector.py*
time_stretch.py*

I think almost all of these cases are better covered at this point by either the specific docstring examples (eg onset detector, beat tracker, or time stretch) or the advanced examples in the gallery (audio effects, demo notebook).

I’d be open to expanding to the advanced example gallery to cover anything crucial that we’d lose by removing the examples folder. What do the other devs think?

Thanks for your input here. I don’t want to tie us to colab, given google’s propensity to discontinue useful services, but it’s easy enough to add examples in the gallery. These can automatically export to notebooks, which ought to be good enough.

Aha! Audio embeds do work, but the only catch is that you can’t stack them using display like in a notebook. I can work around that easily enough.
