#' @title Add additional info to 2D-TPP CCR output data 
#' @description Adds additional info to 2D-TPP CCR output data, like counts on how often a 
#'   certain protein was stabilized or destabilized
#' 
#' @return A data frame to which additional data like how often a protein has been (de-)stabilized
#'  has been attached
#' 
#' @examples 
#' load(system.file("example_data/2D_example_data/shortCCRresults.RData", package="TPP"))
#' shortCCRresults <- tpp2dAddAdditionalInfo(data = shortCCRresults, idVar="representative")
#' 
#' @param data output table returned by the \code{tpp2dCurveFit} function
#' @param idVar character string indicating which column of the data table contains unique
#'  protein ids
