geom_quadrant_lines()

[Pedro J. Aphalo]

To complement stat_quadrant_counts() we need a geom_quadrant_lines() with similar syntax, to be able to highlight the boundaries of quadrants without need to manually fiddle with geom_hline() and geom_vline() when “quadrants” are pooled along x or y axes.

[Pedro J. Aphalo]

Added geom_quadrant_lines() and geom_vhlines().
