Test if it is possible to use the same idea as multipanel Logolas plots to mix Logolas plots with other base graphics plots and ggplot2 graphs.

Add examples of these cases to the vignette if it works.

test_logolas_base_ggplot.R under vignettes.

Having base R graphics with Logolas is still a problem, working on it
