Leaflet: How do you use removeLayer?

If you want to remove the grayscale map from the start just delete:

    "Grayscale": grayscale,

From

var baseMaps = {
    "Grayscale": grayscale,
    "Streets": streets
};

If you want to remove the layer on a click you call it as a method on the map object. Like so:

map.removeLayer(grayscale)

To remove it from the control you first have to assign the control to a variable. Change this:

L.control.layers(baseMaps, overlayMaps).addTo(map);

To this:

lcontrol = L.control.layers(baseMaps, overlayMaps).addTo(map);

Then you can call:

lcontrol.removeLayer(grayscale)

..to remove it from the control.
