#' Calculate Area Outside the Curve
#'
#' \code{AH_AOC} calculates the Area Outside of the Curve for asymmetric boundaries. It is implemented for a variety of techniques and can return bootstrapped confidence intervals.
#'
#' @param dat A Dataset
#' @param input Independent variable
#' @param output Dependent variable
#' @param method What boundary method should be used? One of: SFA, QR, Polynomial, Kernel.
#' @param print_style "ascii" or "r"?
#' @param CI Should confidence intervals be returned?
#' @param nboots Number of bootstraps to generate the confidence intervals
#' @import data.table
