Features: - made to combine with d3 visualizations on map - cache and preload tiles - minimal setup code

To install from source:

Set up http server in dist (eg. cd dist; python -m http.server)

Will try to retrieve cached image tiles starting with current zoom level. If any tiles are missing, then retrieve cached tiles from one level higher (more zoomed in), before retrieving first tile at lower zoom levels for any position.

If no cached tiles are found at current zoom level, cached tiles for a position are rendered in order of rising zoom level, until tile at current zoom level is downloaded and rendered on top.

After all tiles are rendered, adjacent tiles and tiles for lower zoom levels will be preloaded for a more smooth user experience.
