template<class T >
void regionGather ( const LayoutData< T > &  a_local,
const RegionGather a_copier,
LayoutData< Vector< GatherObject< T > > > &  a_gatherObjects 

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.
