Integrate Precond with invint

$tl
	old	operator	new
	doubint C'C		doubint		Unchanged from bei
	symint1	C-C'		asymint1	# antisymmetric integral.
						   Hey, I don't have adjoint!
	symint1 C'C+CC'		sdoubint	# symmetrical double integral.

Precond
	throw out several plots
		data norm and model norm versus iteration.
	include new plot of
		3rd iteration and last iteration.

	throw out non precondition plot

invint
	need symint1 and symint2 ?
