overplot_vertical_lines(x_values, x_labels = NULL, color = NULL,
  alpha = NULL, line_type = NULL, plot_addition = NULL,
  verbosity = NULL, ...)

`x_values`	a vector of estimated quantiles (aka x values)
`x_labels`	meaningful labels to describe the estimated quantiles
`color`	A GGPlot color value.
`alpha`	A GGPlot alpha value.
`line_type`	GGPlot2 line type. Legal values are the strings "blank", "solid", "dashed", "dotted", "dotdash", "longdash", and "twodash". Alternatively, the numbers 0 to 6 can be used (0 for "blank", 1 for "solid", ...). Moreover, one can also use strings that define the linetype with up to 8 hexadecimal digits (each digit specifying the length of interleaved lines and gaps). Reference: http://sape.inf.usi.ch/quick-reference/ggplot2/linetype.
`plot_addition`	Complementary plot objets to be added to the new plot object for enrichment purposes.
`verbosity`	0: no messages. > 0 more and more verbose messages.

A good looking geom object that may be used to enrich plots.
