#' Plot a \code{BootPlot} of a Bootstrap object
#' @param x  object of Bootstrap-Class
#' @param xlabProj character for the x-label title for plot

#' @param xlimi bounds of x-axis
#' @param ylimi bounds of y-axis
#' @param Points logical if is true, the points are plotted
#' @param ... additional parameters for plot (generics)
