OverpassLayer extend Layer

[xeruf]

It seems like quite a bit of functionality is reimplemented as it does not seem to extend the inbuilt Leaflet Layer, and functions such as removeFrom are missing:
https://leafletjs.com/reference.html#layer

Are these sublayers something internal or also externally usable?

Is there an event that is triggered when a layer is hidden because of the zoom level?

Hmm, when I started overpass-layer I just made a class and later I adapted it, to work as a Leaflet layer, but with minimal effort. I guess, this was wrong ;-) If you want to convert it to a real Leaflet layer, you are welcome to do so.

No, if I remember correctly, the Sublayers are only internally. Currently, there's no event which gets emitted, when the layer is hidden due to the zoom level, but it should be easy to add (Sublayer.hideAll).
