Create a PointPattern-class object representing a 2D point pattern with 1,4,5,6,7,8 or 9 points lying in a rectangle.

1	PP2(n = 4, h = 1, v = h, h3 = TRUE)

`n`	the number of points. Must be 1,4,5,6,7,8 or 9. Default, 4.
`h`	the horizontal side length of the rectangle. Default, 1.
`v`	the vertical side length of the rectangle. Default, h.
`h3`	if `TRUE`, alignment of 3 points (see details below) are horizontal (vertical if `FALSE`). Used only for `n`=6, 7 or 8.

When n=4, the four points lie at the four corners of the rectangle. When n=5, the fifth point lies at the center of the rectangle. When n=6 (and h3 is TRUE), four points lie at the rectangle corners and the two other points lie at the centres of the top and bottom edges. When n=7 (and h3 is TRUE), the point pattern consists of 3 horizontal alignments of 2, 3 and 2 points. When n=8 (and h3 is TRUE), the point pattern consists of 3 horizontal alignments of 3, 2 and 3 points. When n=9, the point pattern consists of 3 (horizontal or vertical) alignments of 3 points.
