	-- 1. iTerm2 running, has windows open. Should open a new window for Alfred command.
	-- 2. iTerm2 running, no windows open. Should open a new window for Alfred command.
	-- 3. iTerm2 not running, set to restores arrangement. Should not restore arrangement but open a new window for the Afred command.
	-- 4. iTerm2 not running. No windows to restore. Should open a single window for the Alfred command.
	-- 5. iTerm2 not running. Has windows to restore. Restores windows and then opens a new window for the Alfred command.
