Examples

# 2D neighbourhood
initNeighborhood("2D_N4", method = "calcFilter") # rock neighbourhood
initNeighborhood("2D_N8", method = "calcFilter") # queen neighbourhood

# 3D neighbourhood
initNeighborhood("3D_N6", method=  "calcFilter") 
initNeighborhood("3D_N10" ,method = "calcFilter")
initNeighborhood("3D_N18", method = "calcFilter")
