template<class T>

void regionGather	(	const LayoutData< T > &	a_local,
		const RegionGather &	a_copier,
		LayoutData< Vector< GatherObject< T > > > &	a_gatherObjects
	)			[inline]

Function performs a distance cut-off gather operation.

the input a_local contains a value of T for every Box in the BoxLayout.

the output a_gatherObjects contains all the T objects within the constraints established by the RegionGather object, and the center seperation of their respective Boxes.
