#' @description S3 plot method for object of class\code{"CFA"}
#' @param x object of class \code{"CFA"}
#' @param type character indicating which test to use for visualizing whether the observed pattern are 'Types', 'Antitypes' or not significant at all. Possible options for \code{type} are \code{"pChi"}, \code{"ex.bin.test"}, \code{"z.pChi"}, \code{"z.pBin"} and \code{"p.stir"}.
#' @param fill a vector of (three) colors defining the coloring of significant 'Types' (default "red"), 'Antitypes' (default "blue") or not significant cells (default "grey") in the plot.
#' @param adjalpha character with default \code{adjalpha = "bonferroni"}. Selector for the type of alpha adjustment for multiple testing. Possible options are: \code{adjalpha = "none"}, for no adjustment; \code{adjalpha = "bonferroni"}, for bonferroni adjustment (default); \code{adjalpha = "holm"}, for alpha adjustment according to Holm (1979); other options to come ... .
#' @param ... other parameters passed trough
#' @return a plot visualizing the results.
