Places all hosts in a rectangular grid. The usable area (constraint area minus margins on each side) is split into smaller cells (with separationX,separationY size). Hosts are placed in the middle of each cell. By default, the number of columns and rows follow the aspect ratio of the usable area. By default stepX and stepY are calculated based on the number of columns and rows.
