Plot meridians (lines of constant latitude) on a existing map. DEPRECATED–will be removed by end Sept 2014
mapMeridians(latitude, lty='solid', lwd=0.5*par('lwd'), col='darkgray', ...)

Meridians that will not fit in the plotting space are ignored.
This should use approx
to fill in multiple
segments within the line, so that e.g. great circle lines will be curved.
