◆ norm()

Real norm	(	const BoxLayoutData< FArrayBox > &	A,
		const Interval &	interval,
		const int &	p = `2`
	)

not actually L-p norms, since it doesn't take into account the dx of the system. A user can take that into account or not.

For p != 0, returns pth root of sum of pth powers over all points in all fabs and all components in the interval:

( sum [ |A[i][pt,var]|^p : FArrayBox A[i], point pt in A[i].box(), var in interval ] )^(1/p)

To turn into an L-p norm, one needs to multiply this by dx^(SpaceDim/p).

For p == 0, returns global max over all points in all fabs and all components in the interval:

max [ |A[i][pt,var]| : FArrayBox A[i], point pt in A[i].box(), var in interval ]

Some people don't like that this norm is not normalized based on number of points in A. Normalization is your problem.
