1 2	plotABC(x, OFL, ABC.pstar, ABC.buff, buffer = 0.2, title = NULL, xlims = NULL, save = FALSE)

`x`	- empirical cdf of OFL
`OFL`	- estimated OFL
`ABC.pstar`	- ABC based on pstar method
`ABC.buff`	- ABC based on buffer method
`buffer`	- buffer used for ABC.buff
`title`	- title for plot
`xlims`	- range for x-axis in plot
`save`	- flag (T/F) to save OFL plot to "oflPlot.png".
