/**
	@brief The window behind the "Cable numbering" entry of the
	numbering menu: the one numbering rule the project numbers its
	cables with, the axis those cables are laid out along when the whole
	project is numbered again, and the button which does that numbering.

	The rule is the very editor the project properties hold on their
	cable tab, read from the project when the window opens and written
	back into the project by that editor's own Apply button -- and by
	the numbering button, which writes what the window holds before it
	numbers, so numbering always happens with the rule on show: a rule
	which is changed here is the rule the project keeps, not a rule of
	its own. There is no confirm button of this window's own: what the
	window holds is either applied by hand or left behind when it is
	closed.

	Renumbering works every cable of the project out from the beginning
	of that rule, so the hole a deleted cable leaves in the numbering
	closes -- and it only happens when he asks for it.
