LaTeX: \Sch

	Introduced a new macro

	\def\Sch{\textit{Sch}}

	and replaced all the occurences of \textit{Sch} with \Sch.

Change of base scheme for Algebraic Spaces

	Improved write-up on change of base schemes for algebraic
	spaces. Also tried to spell out better when you can take
	disjoint unions of algebraic spaces.

Algebraic spaces: properties do not change when changing base

	We added a lemma that, basically, will tell us that local
	properties of an algebraic space X over S hold if and only if
	the hold for X thought of as an algebraic space over Z

Spaces: Change of base scheme

	An algebraic space over a base scheme S can be base changed to
	any scheme lying over S. Moreover, given S --> S' then it can be
	viewed as an algebraic space over S'
