						These next two "and nots" tell Minetest not to put the
						red	flame on snow and ice stuff. This "string" bit was
						the workable solution that took many hours, over
						several days, to finally come around to. It's a search
						for any node name that contains	whatever is between the
						double-quotes, ie. "snow" or "ice". I had been trying
						to identify the nodes by their group properties	and I
						couldn't figure out how to do it. The clue for the
						"string"came from Blockmen's "Landscape" mod.
				
						Another quirk is that the "string" doesn't work well
						with variable lists (see "snow_ice_list") when using
						"and not". Ice-fire would light on snow but when I
						clicked on ice, the regular	flame appeared. I couldn't
						understand what was happening until	I mentally changed
						the wording "and not" to "is not" and spoke	out-loud
						each thing that line of code was to accomplish:
				
						"Is not snow, then make fake-fire."
						"Is not ice, then make fake-fire."
				
						That's when I caught the problem.
				
						Ice *is not* snow, so Minetest was correctly following
						the	instruction, "Is not snow, then make fake-fire."
						and that is	why	fake-fire appeared instead of ice-fire
						when I clicked on ice.

--[[
	
	SOME LESSONS LEARNED (and keeping this because I'll forget)
	
	flint_and_steel is registered as a tool. Tools do not materialize something
	like placing a block (on_construct) makes that block appear. Tools are
	*used* so "on_use" works but not "on_construct".

	on_rightclick is meant for the code of the thing being clicked on, not the
	code of the thing doing the clicking.

-- ANIMATED, RISING, DISPAPPEARING SMOKE

--[[

	These next two sections of code are a real bonus that I figured out how
	to pull-off. ;)

	The first section creates animated smoke. Trying to figure out how to make
	the animation appear to go upward was a headache.

	The second section places the animated smoke *only* above the fake-fire
	*if* there is nothing but air straight above the fake-fire. I also made
	the smoke skip a space so it looks more like puffs of smoke and made it
	stretch high enough to be used in chimneys. For large builds, a second
	fake-fire will have to be hidden close to the top of the chimney so the
	smoke will be visible. The smoke also emmits a low-level light.

	Yup, I'm proud of this little addition I've made to Semmett9's mod. :D
