getFlippedGrids()

void getFlippedGrids	(	DisjointBoxLayout &	a_reflectedBoxes,
		Vector< Tuple< DataIndex, 2 > > &	a_boxCorrelation,
		const DisjointBoxLayout &	a_grids,
		const Box &	a_dataBox,
		int	reflectDirection,
		int	reflectCoordinate
	)

function to intersect DisjointBoxLayout with a Box, then reflect it.

The getFlippedGrids function is designed to aid in the construction of reflection boundary conditions. What it does:

For each box in a_grids,

1. intersect the grid box with a_dataBox. If a nonzero intersection, then
2. reflect that intersection Box about the reflectCoordinate in the reflectDirection.
3. create a DisjointBoxLayout of these boxes for which the processor assignments are the same as the origin boxes.
4. Create a correlation list to correlate the DataIndex's of the reflectedBoxes with those in the original DisjointBoxLayout.
