New chapter on de Rham cohomology

Just skeleton so far

Explicit Poincare lemma

	How adjoining a variable doesn't change de Rham cohomology
	provided you can "integrate" functions with respect to the
	variable. This is then used in the proof of the lemma showing
	that crystalline cohomology doesn't change (after inverting p)
	when you add a pth root of a function.

Comparison with de Rham complex for smooth case

	Again we prove this by reduction to the case of a polynomial
	algebra using sleight of hand...

Equivalence crystals and pairs (M, \nabla) for the smooth case

	The current proof uses the case of polynomial algebras. This
	really does seem convenient as it prevents us from having to
	describe the structure of D(n) in the smooth case.
