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.

Gerbe over stack in groupoids

	This is, I think, the correct definition of when a stack in
	groupoids is a gerbe over another stack in groupoids (both over
	the same site of course). It is spelled out completely what this
	means in practice, as well as a nice theoretical description
	in terms of ameliorations as in the previous commit.
