A proof of concept for efficient point encoding in vector tiles

tile.layers.forEach(function (layer) {
layer.id = [];
layer.geometry = [];
layer.tags = [];

/*
@class Control.Attribution
@aka L.Control.Attribution; @inherits Control
The attribution control allows you to display attribution data in a small text box on a map.
It is put on the map by default unless you set its [`attributionControl` option](#map-attributioncontrol) to `false`,
and it fetches attribution texts from layers with the [`getAttribution` method](#layer-getattribution) automatically.
Extends Control.
