◆ get_neighbours()

int CaloRecGPU::GeometryArr::get_neighbours	(	const unsigned int	neigh_options,

Places the neighbours according to the option(s) in neigh_options in the array and returns the number of such neighbours (not the total number of neighbours of the cell).

We're using C arrays for more immediate CUDA compatibility.
