Hello World for .setIcon()

[wboykinm]

Thanks for the clarity of this solution to bindPopup, however I can't seem to use the same logic to apply .setIcon():

I've also tried specifying it in the eachLayer() function as with bindPopup, but that also fails to change the icon. This is surely a basic screwup on my end; what is it?
