Display a grid overlay on a Leaflet map.

Leaflet.Grid needs some CSS to look pretty:

.leaflet-grid-label .lng {
	margin-left: 8px;
	-webkit-transform: rotate(90deg);
	transform: rotate(90deg);
}

Then, after including the L.Grid.js file and creating the map, just call:

L.grid().addTo(map);

You can redraw the grid on every movement (default) or on the end of the movement by setting the option redraw: 'moveend':

L.grid({
	redraw: 'moveend'
}).addTo(map);

• Fix snapping / tick size for small zoomlevels

• Make center fixable
• Wrapping of big longitudes
