1	overlay_points(myplot, lon, lat, col = "black", size = 1, opacity = 1)

`myplot`	dynamic map produced by `plot_map()` function.
`lon, lat`	longitude and latitude of points.
`col`	colour of points.
`size`	size of points.
`opacity`	opacity of points.

all_records <- mysim$record$data_all
plot1 <- plot_map()
plot1 <- overlay_points(myplot = plot1, all_records$longitude, all_records$latitude)
show(plot1)
