#' Wrapper function for cniperPointPlot - Computation and Plot
#'  of Cniper Contamination and Cniper Points
#'
#' The wrapper takes most of arguments to the cniperPointPlot
#' function by default and gives a user possibility to run the
#' function with low number of arguments
#'
#' @param fam object of class L2ParamFamily
#'
#' @param ... additional parameters (in particular to be passed on to \code{plot})
#'
#' @param lower the lower end point of the contamination interval
#'
#' @param upper the upper end point of the contamination interval
#'
#' @param rescale the flag for rescaling the axes for better view of the plot
#'
#' @param with.legend the flag for showing the legend of the plot
#'
#' @param withCall the flag for the call output
#'
#' @return invisible(NULL)
#
#' @section Details: Calls \code{cniperPointPlot} with suitably chosen defaults; if \code{withCall == TRUE}, the call to \code{cniperPointPlot} is returned.
