This layers adds coordinate contours to smooth effect plots. It is mainly useful for smooth-on-the-sphere plots.

l_coordContour(brLO = c(-9:9 * 20), brLA = c(-8:8 * 10), ...)

`brLO`	a vector of meridians to be plotted.
`brLA`	a vector of parallels to be plotted.
`...`	graphical arguments to be passed to `ggplot2::geom_contour`.
