LaTeX: \Ob

	Introduced a macro

	\def\Ob{\mathop{\rm Ob}\nolimits}

	and replaced any occurence of \text{Ob}( with \Ob(. There are
	still some occurences of \text{Ob} but these are sets, not the
	operator that takes the set of objects of a category.

Localization of stacks

	Stacks over C/U are the same thing as stacks over C together
	with a 1-morphism to the stack associated to U (provided h_U is
	a sheaf). In fact there are constructions in both directions
	whose compositions are identity!
