Raster Reprojection d3.carto.map

This is an example of automatic raster reprojection of a tiled layer from d3.carto.map.

It still needs some work. It does not reproject the raster on-the-fly but rather only reprojects it at "zoomend" which is triggered at the end of a zoom or pan event.

This uses Jason Davies' d3.geo.raster and d3.quadtiles.
