util.smqueue: Minor reformatting for code style, add some comments The `smqueue` table (of methods) is no longer exported, as I couldn't see it being used anywhere and it is unconventional (only new() is exported, and methods should be called on the objects returned from that).

if not math.type then

	local function math_type(t)
		if type(t) == "number" then
			if t % 1 == 0 and t ~= t + 1 and t ~= t - 1 then
				return "integer"
			else
				return "float"
			end
		end
	end
	_G.math.type = math_type
end
